Correct. And the spec for a competent cable company is typically 300ft,
as I have shown in the link. Plus the one below.
Believe it or not but I like to have to meet specs in medical because
they protect people. Including you.
Believe it or not, most technical people have that same standard.
You're nothing special.
Never said I was. Except that I do exceed standards at times where I
believe it is necessary. In the case of med electronics that has likely
saved lives. I do not subscribe to the idea that a standard is always
good enough. Because sometimes they are not.
... Would you like to pay
an extra 20% to 30% just so a very few locations can get better
service?
Out here we do not pay extra. Our cable companies out tend do use modern
technology, not cheap stuff from the 70's. A cable company that isn't
competent enough to do more than a measly 100ft would lose their
franchise rather quickly.
Once again the all knowing Jeorge shows his ignorance.
No. I suppose you know what MoCA is. Do you consider them ignorant?
Because they say the very same thing that I said. What matters is
today's state-of-the-art. Nobody cares about what it was in the 80's.
Today this is state-of-the-art:

Did you miss: "IN THE NEXT DECADE"?
Quote "The Multimedia Over Coax Alliance (MoCA) provides a standard ..."
then
Quote "The maximum cable distance supported between the root and the
last outlet is 300 feet, with a maximum attenuation of 25 dB". And this
is for MoCA, not just cable TV.
1: You don't know what you're talking about, about the cost of
service. Any extra operating costs become part of the basic service
that everyone pays. You won't work for nothing, and the utilities don't
give them free electricity. The service companies don't repair the
equipment for free. Do you have any idea how many amplifiers, taps and
set top boxes are needed for 10,000 active ports? To provide hotter
ports require more amplifiers, and raises the system noise floor. You
'designed an amplifier'. Big deal. A lot of engineers 'designed and
amplifier' and those companies are long out of business. ...
So how many linear RF amplifiers above 1W have you personally designed
and guided through layout?
Hint: All my clients are still in business and I am sure will be for a
long time to come.
... Current CATV
amplifiers use hybrids designed specifically for the application and
they use them for many reasons. That just leave the design of the 60V
modified sine wave to DC power supplies, equalizers, gain control,
equalization and remote switching. Some locations also have remote
monitoring so the headend can check system status on a continuous
basis. It can also report outages when some of the equipment doesn't
respond. They can even detect power failures and monitor the battery
status in the standby power supplies to give them time to get a portable
generator to the area if it is an extended outage. The local
Brighthouse system remained in operation here for over four weeks after
a hurricane even though the only way to watch TV or access broadband was
with battery power or a generator.
If that company can't do more than 100ft they'd fail miserably in our
market. It's not just our house, it's also the neighbor to the west, and
the one after that, and ...
2: '70s CATV tech was 12 channel with no return path. It was crude,
discrete point to point designs that looked like a ham put together from
junk TVs while drinking cheap beer. They were touchy as hell, their
tempco sucked, and they were impossible to service without a fully
equipped test bed. the power supplies were simple, poorly regulated
linear supplies with 85 C electrolytics that died quickly in the
southern sun. The large diecast aluminum housing ran hot to the touch
without the sun hitting them. That stuff was pretty well all scrapped
out by the mid to late '80s by 36 or more channels with return
capability. There was so much construction of upgraded systems that
there was a severe shortage of new hardware through most of the mid
'80s.
That '80s tech was gone in all but the smallest systems by 2000.
Today most systems are 450 MHz or higher, and are 'Fiber Enhanced' to
provide telephone, broadband, movies on demand and pay per view services
by breaking the system into cells that cover a few hundred homes, or
less.
3: You know nothing about CATV franchises. 'A measly 100 feet' is
more than adequate for a hell of a lot of drops & house wiring. ...
No, it is not. If you don't believe me check out Cameron Park, CA,
especially the area of the Estates. Then tell me how you want to do that
with 100ft drops.
... If that
is what the franchise calls for, THAT IS THE SPECIFICATION, ...
And the franchise would get kicked out of the market around here. You
can't serve this market with a sub-par spec. The big automotive
companies had once exhibited a "Well, this is the spec and that's that"
attitude like you do in this thread. Then they learned, the hard way. In
part by essentially going on welfare which was embarrassing.
... no matter
how much you whine like Sloman. A city or county won't pull a franchise
over one or two people complaining about weak signals. ...
They will if there's a whole big crowd showing up at the next meeting.
Now I won't because I only watch the evening news via antenna. But I
know a whole lot of folks who would be miffed to be declined service
because they are literally addicted to the sports channels. Many would
just get satellite though, they market that quite aggressively these days.
A big crowd is what percentage of their customer base?
... They receive a
fixed percentage of the system revenue every month, and the percentage
was set when the economy was up. If they pull the franchise, another
provider will offer a much lower percentage. It also involves legal
fees, and causes the rates to go up for the users.
The county folks have one much more important thing on their mind: How
to get re-elected. That's what'll matter most to them. They know that
seeing complaints about what many people perceive as a utility service
they have "rights to" in the paper is not the way to get re-elected.
No one has a 'right to' cable TV. I was at one meeting where a
citizen was demanding that they revoke our franchise. They told him
that one complaint out of 10,000 customers wasn't enough reason to
revoke. he was as arrogant as you. Everything had to be his way. He
got really ****ed when they told him to buy a satellite dish and go
away. His demand was a s ignorant as yours. He was demanding that he
bring back CBS ARTS, and wouldn't listen that CBS had dropped the
service. One other complaint was from a woman demanding that our
franchise be pulled because CSPAN was down for a couple days during the
modification of a 5 meter dish to multiple feeds.
... Why put up with all
that for a fraction of a percent of problems. Like people who built a
private road a mile long and want to pay the standard install fee when
it will cost about $15,000 to run a feeder for that one house. Or like
that marina. It isn't a street. It's private property. If they want
better service, let them pay for upgrades with .500 cable to each boat,
with a .500 to 'F" connector for each boat. That would only cost a few
hundred dollars a boat for materials. More if the cable is jacketed.
If it isn't it won't last long in salt air. Double that for the
hardware and labor to get a good idea of the costs.
Then answer a question I asked you before but you did not comment on it:
Why did Mike's cable provider not decline service? Obviously it worked
reliably in the analog days and now with DTV it doesn't. If they can't
handle the 170ft drop after the digital switch, why did they not inform
Mike, cancel the service on their part and send someone out to pick up
the set-top box?
Sigh. Just because there is a new agreement for the industry doesn't
mean that all existing have to comply. Some companies are FIOS. By your
standards, everything else should be replaced overnight. Then the
distance won't matter at all. I doubt that the income from that marina
will ever pay back the construction costs. the system worked for
analog, when it was installed. There are no guarantees in life. Stop
trying to walk on water, you'll drown.
