Default RG-6 QS, top brands?

Twist-in connectors do not provide the shielding that a CATV system needs.
They are a HUGE source of ingress/egress, and the return loss is rather low
(the higher the better. Hex-crimp fittings have ~18dB, and compression are
30dB). Plus, It actually takes more time to put on a twist-on connector

that it does to put on a real connector.

Compression fittings may cost a little more for the connector and the
installation tools, but cost less in labor (time) to install. Not to
mention the materials/time spent in replacing the twist-on connectors with
real ones when they don't work properly.

I am just trying to get an updated list of the top brands of RG-6 quad
shield coax cable. I have seen posts from a few years back mentioning
Belden, Carol, and Commscope, but I just wanted to get an updated
list. I have seen Carol and Zenith brands at local stores recently,
are these any good? Mainly going to use this cable for running feeds
from HDTV & analog TV antennas in the walls of a house.

My experience with a few Carol Cable products (including coax) has been
good. I would consider that the Zenith brand name appears to be rented
out to the best bidder these days (peruse a.h.r for recent stories about
Heath/Zenith products) and expect that the manufacturer spent most of the
cost of making that coax on the marketing of that coax.


Belden, Alpha and Carol are all good. As important as the cable are
the connectors. The compression type are the way to go, IMO. Invest
in a good QS stripper and a compression tool. Don't bother with crimp
tools and don't even think about twist-on.

Hi Paul

What is the problem with "twist-ons"? I dont question your judgement,
but I have found them to be good for my 2 meter application.

Now I am considering doing some work at 2 GHz. This is a good time for
me to learn about cable and F connectors.

Thanks
