RG-6 QS, top brands?

Post by szilagyi » Sat, 07 Apr 2007 02:53:35

Hello,

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.

Thank you very much for all feedback,

Chris

Just do not worry about the cable; put 1/2" or preferably 3/4" ducts in the
walls.

Never place RF (or any) cable directly in concrete or masonry. If, for some
reason, you end up with a bad cable (soaked with rain water for instance)
you just have to pull it out and replace it. So you don't really need to go
for top brands and overrated and expensive cables.

If you intend to place short stretches (less than 10 or 15 meters) for the
VHF range, use RG6 with solid polyethylene dielectric. If you have to place
important lengths for UHF of satellite MF bands, use RG11 with polystyrene
or foam dielectric. I used train loads of Commscope cable without to many
problems. They gave weird names to their cables like 6ST??? for RG6 type and
11ST??? for RG11. Always use RF cable with copper clad core as they work
best with F type connectors. Stay away from jacketted cables with "flooding
compoud", even for underground placement.

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 1694A is a nice cable, as is Canare L-5CFB.

I built a component cable set for my front projector out of the Canare
V3-5CFB, which is basically similar to the L-5CFB but has three cables
wrapped together in a single jacket.  Works very well.

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 *** 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
                             Jerry

Two reasons I don't like twist-ons.  First, I don't find them to make
that great of a mechanical connection and can therefore be pulled off
the cable fairly easily.

Second, and I admit I don't have network analyzer plots to back this
up or anything, I've always found them to make a mess of the shields
when you twist them.  That could lead to more of an impedance bump at
the connector than with other types.  Probably not an issue at 2
meters, but more important as the frequency goes up.

If you can pull them off, you are probably not putting them on
correctly.
(Tip: Ignore instructions, and use cunning.)

While the connector thread will crush the outer somewhat (causing a very
short piece of low Zo), it's unlikely to be a problem in most
applications, even at 2GHz.

What's the diff between a compression tool and a crimp tool?

OT: I inherited break/fix responsibility (billable by the hour) on a
business thinwire lan that was installed by a TV cable guy. He used
twist-ons and no crimp rings.  That site paid my rent for a couple
years, until I eventually replaced all the connectors with proper
ends.

For that reason, I've always looked fondly on twist-ons, in a bizzare
way.

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!!

it not that they are so bad it just that the compression fittings are the
way to go.

The compression fitting have a captive sleeve on the cable end of the
fitting.  You strip the cable more or less as usual, slide it up
through the connector as you would with a crimp type.  But then the
compression tool presses the sleeve up into the body of the connector.
The inside is tapered, so when the sleeve is pressed in, it compresses
against the cable, locking it tightly into place.

Here's a picture:

They are also available with seals for water resistant outdoor use.
(In fact, the picture is of a connector with seals.)

Here's what the tool looks like:

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.

OK. It's a large, well engineered crimp tool and fitting.  

I actually have tools, some cable, and a bag of ends that fit that
description.  I just considered them standard tools and parts for
serious work.  They came to me by accident. I was the "customer" for a
a pre-ethernet LAN built on CATV plant that spanned a 40 floor
building.

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.

Go to http://www.redwaveradio.com/
Pages 12 & 13 illustrates why you don't want to use hex-crimp fittings.
