[Boatanchors] Boatanchors Digest, Vol 108, Issue 5

[D C _Mac_ Macdonald]

As is said, "Aye, and therein lies the rub!" 
 
Availability of adequate connectors to use between 
the CATV cable and our "normal" connectors used for 
jumpers. Very few have the skill and/or equipment 
to build those interfaces.

> A couple of years ago, I acquired (leaglly!!) thousands of feet of brand new Comm-Scope CATV hardline. This stuff CANNOT allow water ingress and I have had zero problems with anything.... I still have rolls of 5/8", 7/8", 1 1/4" etc...

> Right now, I use 5/8" CATV stuff for my tribander at 95' up
> 7/8 " for 6, 2 and 432. I use mast mounted preamps on 2 and 432.
> I have a small machine shop and make my own CATV to coax connectors from 6061-T6 billet.
> The built in antenna tuners on my HF and 6 M radios will instantly 'tune' the 75 ohm stuff to 1:1. Trying to make matching sections etc, to transform the 75 to 50 ohms is not worth the problems with connectors, etc.
