not convinced the latter was even working properly).

This is a residential location with no high structures nearby. I believe

For a 10 year old TV with a converter box in one location, a simple loop

For a new HDTV at the other end of the house, nothing I've tried seems to work
very well, with some channels requiring very careful fiddling with the
antenna orientation to be acceptable most of the time.
Reception on analog channels is fine and I believe the TV is working correctly.

According to http://www.antennaweb.org/ , for most of the channels I
care about, a "small multidirectional antenna" should suffice.
I haven't yet tried an antenna like and would hoping for recommendataions,
or whether it would even work.

I realize this is insufficient information for anyone to suggest a
specific remedy other than "get a wired connection", but figured it

FWIW, I've heard that most DTV transmitters are on reduced power until
the transition, which may improve things....

I'm getting everything that's available, with very clear reception.

Secondly, converter boxes and TVs differ on their sensitivity. Some digital
TVs receive weak signals much better than others. Same story with converter
boxes. A good indoor antenna and a good, sensitive converter will work
wonders.

Finally, it's true that *some* of the DTV channels are at reduced power now,
but not all. Things will improve *somewhat* come February, but not on all
channels. A good antenna and a sensitive converter box are your best bet.

If you can fit a big outdoor antenna into the attic, just laying it on the

work very well, especially indoors. A mast and rotor outdoors are the

Jim,

Both of those channels have relocated their DTV transmitter sites
quite a distance from their original analog sites. Chan. 2 (and chan.
55 when they were still on) broadcast analog from Orange City. Chan.
15
broadcast from west of Daytona Beach. Being a college-based station,
they don't run much power or have a particularly tall tower. I get
snowy, but watchable, reception on 15 in the NE suburbs of Orlando
with a large
rooftop Yagi.

All the central Florida DTV stations have located their DTV
transmitters at the antenna farms east of Orlando, where the Orlando
analog TV and FM stations broadcast from. Channel 2's DTV signal is
actually on Chan. 11, and Chan. 15's DTV is on either 30 or 33. Chan.
68's (college-based PBS out of Melbourne) DTV is on the other. One
advantage to this is that you won't need a rotor to pick up all the
available DTV stations as they
are all broadcasting from the same location. The downside is that
Daytona and Melbourne are at the Northern and Southern ends of the
Orlando coverage area, and the analog stations gave folks in those
cities a strong local PBS signal. With DTV, they will lose the local
signal, and Orlando will end up with three PBS channels.

DTV's claim was for an improvement over NTSC..in picture quality,and for
better use of existing bandwidth(subchannels).

Sam:

It might help us if we knew approximately where you live, and the
directions/distances of the signals you are trying to pick up. A good
antenna in the attic with a distribution amplifier as suggested
earlier should work pretty well, especially if the antenna can point
out the gable end of the roof, and you do not have aluminum siding.
Getting a signal thru regular roofing shingles works ok when the roof
is dry, but there is a lot af attenuation when the roof gets wet or
snow-covered as it does here in IL where I live.

Five Orlando FM stations were located on the Ch 55 tower in Orange
City when I was a Broadcast Engineer there. They had an eight port RF
combiner that could handle 50 kW per port, and a curtain antenna at
about 1000 feet. One RF engineer worked for all five stations, and
lived on site so things could be repaired as quickly as possible.

I can't see either TV station abandoning that site, since it is the
tallest tower in Central Florida. It is taller than the Ch 2 tower on
the other side of Hwy. 17/92, and was the tallest at 1200 feet, prior to
the Ch 55 tower's construction.


Channel 2's DTV signal is
actually on Chan. 11, and Chan. 15's DTV is on either 30 or 33. Chan.
68's (college-based PBS out of Melbourne) DTV is on the other.


That PBS station on Ch 68 was on Ch 18, and traded allocations in
exchange for Ch 68's crappy NEC transmitter. It was originally
installed in Orange City, on the same 1749 foot AAT tower that Ch 55
used. BTW, Ch 55 owns the land, but not the tower.


One
advantage to this is that you won't need a rotor to pick up all the

The analog Ch 55 signal covered all of Central Florida, all the way
to the gulf, and I got one reception report from Texas.

If that's true, then it's likely that your house is RF shielded either
by chicken wire in the walls (stucco) or aluminum foil backed
fiberglass insulation. If so, there's no hope for an indoor antenna.

Try a cheap and simple experiment. Take a length of RG-6/u CATV coax.
Strip back about 20" of the outer jacked and shield. Shove it out the
window, hopefully on the side of the house that faces the TV xmitters.
Crimp an F connector on the other end and connect it to the TV sets
antenna connector. This is a truly attrocious TV antenna but should
work in a strong signal area by moving the antenna outside of your
shielded house. If it works noticably better, you might consider a
better outside antenna, which should improve reception even more.

If you live in an apartment complex, you might consider inspiring the
landlord to resurrect the rooftop community TV antenna system, and
distribute the signal to the entire building. Most CATV coax
distribution system come together in some manner of utility room. It's
easy enough to disconnect your coax cable from the cable company and
reconnect it to a community antenna system.

or HDTV signal. For those that had/lost a snowy/fuzzy analog signal, hardly
a step forward. Or for those companies (read: Comcast) that are using the
consumers confusion/bad luck to their advantage.

Cute. That should work. However, such antennas are not all that
expensive:
http://www.antennasdirect.com/DB4_HDTV_antenna.html $50.
The problem is that they're UHF TV (14-69) only. If you're trying to
receive the VHF channels (2-13), then you'll need a 2nd or a different
antenna.

If that's true, then it's likely that your house is RF shielded either
by chicken wire in the walls (stucco) or aluminum foil backed
fiberglass insulation. If so, there's no hope for an indoor antenna.

Try a cheap and simple experiment. Take a length of RG-6/u CATV coax.
Strip back about 20" of the outer jacked and shield. Shove it out the
window, hopefully on the side of the house that faces the TV xmitters.
Crimp an F connector on the other end and connect it to the TV sets
antenna connector. This is a truly attrocious TV antenna but should
work in a strong signal area by moving the antenna outside of your
shielded house. If it works noticably better, you might consider a
better outside antenna, which should improve reception even more.

If you live in an apartment complex, you might consider inspiring the
landlord to resurrect the rooftop community TV antenna system, and
distribute the signal to the entire building. Most CATV coax
distribution system come together in some manner of utility room. It's
easy enough to disconnect your coax cable from the cable company and
reconnect it to a community antenna system.


If the wiring is owned by them, they can. Most of the apartments we
served were wired by our cable company, and the contract with the owner
stated they had to buy it from us, if it was to be used for anything
else. The few that had existing wiring were done with either 300 twin
lead, or single copper braided shield RG-59, neither of which would pass
the FCC leakage requirements. Some mid band channels could interfere
with aircraft communications, and others would wipe out two meter
Amateur radio, or high band VHF communications. Since the cable
company would have to opay the fines, they simply didn't use owner
supplied wiring, if it didn't consist of new, approzed materials.

Most of the buildings had locked wiring cabinets, as well.

You are too susceptible to hype.
This wasn't about *better* (as we see, for many it will be WORSE);
DTV is all about **more profitable**.

Bingo!

I guess it is a step forward for the manufacturers of
DTVs, antennas, and other video equipment,
and cable, fiber, and satellite content providers!

Now you're on the beam.
Those commercial interests lobbied hard for DTV:

There's the subscription-based distribution industry
-- Rural viewers who could previously get by with a snowy picture
may now need satellite dishes to get anything
and folks who weren't too bothered by multipath (with analog)
may now need cable/sat.

....then there's content providers -- Digital == ***DRM-capable***

Of course, guys in the electronics services industries
can also cash in on DTV boondoggle
by getting savvy in exactly the theme of this thread:
What do I, Joe Consumer, need to watch terrestrial DTV reliably?

My feeling is that (very local) CATV is about to see an upswing.

The analog shutdown in Wilmington, NC will be a useful boilerplate.

There are plenty of other things in the home that block RF besides
chicken wire under the stucco and foil backed insulation. Some
decorative wallpaper has a sheet of thin foil inside. Aluminized
mylar energy efficient windows are an effective RF block. Metal
window and door screens block RF. If you live in a poured concrete
structure, where the inside walls are also concrete, the water in the
concrete will form an RF barrier. Antennas in the attic work
usually well, but if the roofing material is metalized (i.e.
reflective), no RF will pass.

I run into such things all the time with Wi-Fi, where barriers to
2.4GHz is more pronounced than at TV frequencies. A really good way
to test for a problem is to check for indoor cellular coverage. If
cellular works well outside or close to an open window, but the signal
drops severely elsewhere inside, then there's metal in the walls.

OK, some more info:

House is about 90 years old without many modern upgrades. First floor
stucco, second floor redwood siding. I doubt there is any sigificant
insulation (that's for another group and another thread!) or anything
metallic in the walls.

All TVs get excellent analog reception.

TV/DTV convertor box on second floor on side facing antenna farm gets decent
digital reception with only old UHF loop.

TV/DTV convertor box on first floor has basic Radio Shack antenna and now
seems passable but not gerat.

Antenna is placed on top of china closet in dining room.

New Toshiba LCD DTV on opposite side of house is the main problem.
(But analog reception there is so good that a casual observer might think
it is a DTV signal on most channels.)

I like the idea of an experiment hanging a wire outside the house to
see if that helps, though it's on the wrong side to be really effective.

Attic is full of junk (I bet you're not surprised), so plopping large
antenna there is probably not an option, though there is a crawl space
that is empty.

Yep. We have a local repeater output on 145.25Mhz, which is dead on
the CH18 CATV video carrier. The local system leaks somewhat and I
can barely hear anything. Worse, the various subcarriers are landing
on other repeaters. I've complained, but haven't pushed the issue.
Driving around listening to 145.25 shows that there are at least a

Since the cable

I checked the recent FCC rulings. One fine for CATV leakage found in

It depends on how it's packaged. These days, CATV wiring usually gets

Tell them were the leaks are, and suggest they fix them before the
FCC gets a written notice about interference to licensed radio users.
We had 'sniffer' receivers in our service trucks, and the techs were
required to report any radiation to their supervisor so he could
investigate the cause with the spectrum analyzer & bucket truck.

The wall cabinets we used were steel, and you would have to drill the
lock, or use a cutting torch to get inside. Any physical damage could
result in termination of servixce to the entire building, or even all
apartment buildings belonging to the same company or individual.

If you can fit a big outdoor antenna into the attic, just laying it
on the
attic floor usually works quite well. Nothing small and convenient

work very well, especially indoors. A mast and rotor outdoors are
the
thing to have.

With DTV, computer DVRs are practical - I have 4. If the rotator moves

would survive even lower signal levels.

A set of rabbit ears and loop antenna sufficed.

Now, as expected, with DTV, it's either there or it isn't, and even with
the built-in signal strength display on DTVs and converter boxes, it has
become a royal pain to tune in many channels.

The assumption today is that one will use a wired connection so DTVs
usually don't even come with any sort of indoor antenna.

Now, this could probably start a lively discussion on the politics and
economics of the DTV conversion and that's just fine.

But, what I would like input on is what sort of indoor antennas might be
best to use in what is basically an area which should have decent signal
strength for the channels I care about.

So far I've tried using old loop antennas and basic indoor antennas (loop+
rabbit ears) from Radio Shack, both unamplified and amplified (though I'm
not convinced the latter was even working properly).

This is a residential location with no high structures nearby. I believe
most of the transmitters are only a few miles away.

For a 10 year old TV with a converter box in one location, a simple loop
antenna seems to be fine. For a similar setup on the floor below,
reception is terrible on nearly all channels no matter how the
antenna is oriented.

For a new HDTV at the other end of the house, nothing I've tried seems to work
very well, with some channels requiring very careful fiddling with the
antenna orientation to be acceptable most of the time.
Reception on analog channels is fine and I believe the TV is working correctly.

According tohttp://www.antennaweb.org/, for most of the channels I
care about, a "small multidirectional antenna" should suffice.
I haven't yet tried an antenna like and would hoping for recommendataions,
or whether it would even work.

I realize this is insufficient information for anyone to suggest a
specific remedy other than "get a wired connection", but figured it
might be worthwhile to hear about others' experiences so far.

Thanks!

I am so surprised that no one has mentioned the (to a bunch of people,
anyway) best site for antennae information:

http://www.tvfool.com/

Both analog and digital information is available along with a .png
file for either, or after the February 2009 cutover. The Kw ratings
and db figures are there, along with the actual and virtual channel
numbers.

Someone did a very good job
