I installed a Channel Master 2016 antenna on my roof
I now need to run coax from it to the inside of
house.... about 50 feet I think
Is RG6 quad shield the better choice over plain RG6 in
most cases? The price diff isn't that much actually.
If yes, why?
If I found that twin-lead worked, I'd still got with RG6. I'd lose a
little signal strength in the transformer and the transmission line, but
HDTV doesn't seem to need much signal strength.
With HDTV, anything that breaks the digital train can interfere with
viewing. Coax is less affected by rain, sun damage, proximity to metal,
and RF interference. Apparently the quad shield was developed for
greater reliability, so I'd go with that.

Shielded "foam" twin lead is usually the best choice for antennas from
my experience. Way back in the olden days when you had to get a
Richmond station (from DC) to get blacked out Redskin games, that was
the lead in of choice for our 60' masts.

Quad shield might have lower loss than regular RG6. Even though its
only 50 feet cable, if you have marginal signal strength, it might be
the difference of getting a picture or not. Keep in mind most HD
channels operate in the UHF spectrum which is more sensitive to cable
loss. For example, for analog channels below 450Mhz, the loss might be
2 db per 100 feet, but for UHF 450Mhz and up the loss could be 5-6 db
per 100 feet. So getting the right cable helps, and also keeping it as
short as possible.

I'd use the RG6QS with Thomas Betts Snap-n-Seal connectors, you'll
never have a problem with signal loss, interference or water. Make
sure you get connectors compatible with QS also. When I wired my
house 10 years ago the price difference was so small I used QS and
have never had a weak signal going to 10 rooms via a distribution amp
in the basement. Both are just as much work why not do the best?
