[TowerTalk] F-connectors

[Jim Brown]

Certainly not reason -- SnapNSeal makes crimp BNC connectors to fit most 
CATV coax.  I have some!  AND -- RG6 does NOT define the size of coax, 
nor the shield, nor the center conductor.

Indeed, there are many variations of CATV coax -- there are some 
designated RG59, RG6, and RG11, and within those designations are solid 
copper or CCS steel shield, variations in the number and type of shields 
-- everything from a single foil, single foil plus single braid, and 
dual foils with dual braids. Virtually all shields for these CATV coaxes 
are aluminum.  AND each RG-number and each shield type require 
differently sized crimp connectors.

Not only that, but there are multiple grades of F-connectors. Poke 
around the internet for SnapNSeal and Belden are two of the better brands.

The primary reason for using F-connectors is that the CATV cables 
require crimp connectors, and F-connectors have dominated CATV/MATV 
because they are fairly inexpensive and very easy to install with the 
proper tools.  Back in the '70s, one of my gigs was installing CATV/MATV 
systems in Chicago high-rise buildings, include Sears Tower. The 
connectors we used then were quite primitive as compared to those in use 
today.
