OK, Bob E - it appears that the ball is in your court. In the interests
of peace and harmony, and to prevent confusion, please could you please
tell us exactly (and I mean EXACTLY) which RG-6 vs RG-6Q parameters you
are concerned about?
Ian

OK, thanks for the discussions.

I have a VHF/UHF omnidirectional antenna with integral amplifier for TV
reception:

Several broadcast towers surround me, from 40 to 50 miles:

Terrain is pretty flat.

The antenna is currently connected to RG6 located indoors, up high in a
1-story cathedral-ceiling home. Signal reception is marginal, gauged by the
HDTV's (relative) Signal Strength display; dropouts occur regularly on some
channels.

I plan to mount the antenna outdoors on the peak of the roof. I was planning
to use RG6 quad-shield, but wanted to check whether it is truly a better
solution or not.

Cable run indoors now is about 50 ft. From the roof location this will
increase to 75 or 100, depending on the route I choose, hence my question.

Thanks.
