You'll wonder how you ever did without them. Ebay is a great source
for compression fittings. Keyword Digicon. I got my first tool for
Thomas and Betts and the T&B system. When the fittings became pricey,
I switched to Digicons. Since I didn't want to convert my tool all
the time, I grabbed an LCCT tool and fittings. My guy in the Detroit
area (about 50 miles away) sells me a few hundred at a time. I paid
$108 with shipping for 300 the last time and had them in about 30
hours from the time I placed my order.

Belden and Commscope are the top names in CATV/Satellite cables and
compression connectors are now the standard for all satellite installs.
T&B Snap-N Seal is considered the best of the compression connectors.
The two big satellite companies not only spec compression connectors but
also solid copper center conductor RG-6 due to the lower DC resistance
for powering equipment down the cable. If you use say, Belden 7915A
cable and T&B SNS1P6U connectors, nobody can ever say you skimped.

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,

Don't forget Times Fiber at the top right there with CommScope and Belden.
As far as compression fittings, Snap-N-Seal definitely is in the top group,
right along with PCT, Digicon, Gilbert, & PPC. The whole shebang started
with PPC.

Yep, that's the tool, here's the reference to my Detroit Connection

Times make great cable but I don’t see any used in CATV or direct to
home satellite installs in my area. If you get the Ripley CAT Universal
tool for the RG-6 compression connectors it will fit all the brands you
mention.

cool. I already got the green connector today from another seller $16 for a
hundred plus $16 to ship G . Still a deal. Going after the tool now.

thanks for the info.

I started using Times when I started in cable in '85. Have used the other 2
aforementioned brands, but still spec Times for our systems.

That tool, as well as three of the ones listed here
http://www.cencom94.com/gpage.html2.html (CT-FBR, PCT-DRS-CT, &
PCT-DRS-CT-AS), Cable Pro's LCCT-1, and many others fit those fittings.
Only sort of exception in that group of fittings is PPC. They originally
started out with the EX Series, which is about 19mm in length. Then others
started making compression connectors that were 21mm in length, which is
what the majority of them are. A few years ago, AT&T Broadband pushed PPC
into making a 21mm fitting, which they labeled EXXL. PCT also has a
Universal connector (TRS Series) which is a different length.

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.

Funny how it works where a bad connector will blank out just a couple of
cable chanels. First time this hapened to me about 20 years ago the cable
guy came out and said it was a bad connection. Almost laughed at him,but he
replaced the connector at the outside of the house and it cleared right up.


Very good info. The interesting thing is since my original post I
went and bought a 500 ft roll of Carol Brand RG-6 QS from Home Depot,
and made some cables with the crimp-on connectors I already had. When
I swapped these new RG-6 QS cables with ones I made a while back with
regular RG-6 with the same crimp-on connectors, I got surprisingly
horrible results. A couple of analog channels don't come in at all
(ch 28 and 56), where they used to come in with a fairly good picture.
Yet other channels on lower frequencies, such as VHF appear to be the
same. I inspected the connectors and they appear to be OK, but I am
guessing there must be an issue with these connectors and the RG-6 QS,
where it's causing the issues that were described above with loss. Is
this possible?? It seems to be affecting various UHF channels (ch.
28, 56, 62).

Thank you very much for the help.

I've worked in the cable TV industry for nearly 44 years, and have NEVER
found that a certain type of male F-connector is, in itself, responsible
for 'horrible results' in terms of RF throughput. Provided that (a) the
shell makes good contact with a few strands of the braid, (b) you
haven't managed to wind a strand of the braid around the inner
conductor, and (c) you haven't left a thin film of the dielectric on the
surface of the inner conductor (yes, I've done all of these!), the
connector WILL appear to work normally. All that suffers is the
screening effectiveness and mechanical reliability.

Regarding whether some male connectors create a significant mismatch due
to crushing of the dielectric, even if this does happen, is not going to
be significant in normal use (up to at least 2GHz) until the outer
conductor is almost touching the inner. You can easily prove this for
yourself by looking at the RF throughput of a piece of coax, while
progressively crushing it with a large pair of pliers.

The thing which causes the most noticeable impedance mismatch is
normally the female part of the connection. Connectors with a
'duck-bill' inner (two parallel fingers) tend to be more capacitive than
those with a 'tulip' (three or four fingers). They are also likely to
make a less reliable ohmic contact.

Don't get me wrong. I do not advocate sloppy practices when fitting
connectors. In the UK, the compression and 'snap-and-seal' types are the
de facto standard. However, I would not hesitate to use crimp or
screw-on types for home use, provided you know how to fit them properly.
And I do.

At a trade show several years ago, a vendor demonstrated the effects
stapling cables could have on signal transmission. He took a VCR, a ch. 3
modulator and a piece of drop cable and attached the cable to a piece of
wood utilizing a regular staple gun that you buy at any home improvement
store. Used the gun as most people would, and inspection of the cable
showed it to be fine (undamaged). By the seventeenth staple, ch. 3 was
completely gone..

It doesn't take major crushing to create mismatch, and as to whether it is
significant sort of depends on what happens to be trying to get through at
the particular point where the mismatch occurs.


At http://www.cencom94.com/gpage.html9.html, there is a picture of a sweep
trace of some cable with hex-crimp connectors (gotta scroll down a little).
