Hex-crimp fittings have 6 points where the connector is pinched into the
cable creating small impedance mismatches. Impedance mismatch creates
reflection. If the reflection(s) is(are) severe enough, whatever is at
that(those) frequency (frequencies) may not work. Plus, their return loss
is a fair amount lower than that of compression connectors (~18dB as
compared to 30dB).

I've replaced hex-crimp fittings on DirecTV systems because of hex-crimp
fittings which were causing some channels to not work.

Pages 12 & 13 illustrates why you don't want to use hex-crimp fittings.

I am just trying to get an updated list of the top brands of RG-6 quad

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.

What are the common issues with the crimp-on connectors? I've been
using them here and there mainly because they are cheap. So far I
haven't really noticed any problems, but maybe it's because I haven't
used anything else to see an improvement. Thanks!!
