My drivel:
At my home, knology recently upgraded there system for faster internet.
A cableman said he heard me radiating a block away. he came in and
changed 7 crimp type connectors in my attic a couple of cable runs.
Speedtest.com went from 6 Mbps to over 11 Mbps with just those changes.
Yep, that's the way it works. Compression type F connectors work
well. Crimp type are junk. The catch is that there are probably 100
different types of connectors, each with their own compression tools,
intended to fit about 8 different types of 75 ohm coax (RG6a/u,
RG59/u, single shielded, double shielded, quad shielded, direct
burial, etc). Mixing connector types and cables doesn't work. I got
fed up and "obtained" a 1000ft roll of double shielded RG6a/u, a big
of matching F, BNC, and phono connectors, a compression tool, a
stripping tool, and replaced all the junk cables in the house.
If it's Comcast, you will probably still have the lower 72 channels
doing analog. Remove the set top box and plug in your TV directly.
Oh, if that is the fact, I may get me some browny points, If I can get
the signal up to snuff, then put the vcr back in the line, my wife could
record her soaps again.
That would get me 15 seconds of hero status!

I'm sure it's true for Comcast in Santa Cruz, CA. No clue on other
areas. The grand plan is to move all the analog channels to digital
area by area:

http://www2.newsadvance.com/business/2011/nov/09/comcast-switching-analog-digital-ar-1448489/
Unfortunately, your area may be one of those that have moved to all
digital. Hard to tell from here.
Just an addition to the termination debate, the marina has about 150
taps, I'd be surprised if 30 of them are connected to a tv and the rest
are unterminated. The line generally goes to the utility pedestal into
a 2 way splitter and then about 1 ft of cable connects it to the 2 taps
for the boat owners.

Can you determine if the marina is using a distribution amplifier
driving a big splitter, or is using a single cable trunk snaked
through the marina, with taps (directional couplers) at various
points? If taps, it's easy to install too many taps, or miscalculate
the tap type, resulting in level variations along the trunk.
