[TowerTalk] Splice 1/2 in Hardline?

Wed Jul 13 09:22:59 PDT 2011

No way to install the underground part in conduit?

I've given up on trying to keep critters, people, water etc. out of 
underground cable.  We just put it all in conduit these days.  It's not that 
expensive and allows a LOT of flexibility.

Also, I've noticed that silicone will tend to corrode the inside of a 
connector when it's used.  I used to goop up clearance challenged connectors 
with silicone then put heat shrink over the top of that.  Those didn't last 
long.  Sure seemed like a good idea at the time though!

Perhaps the HAM bands are just that much less sensitive to water etc. than 
the 2400MHz and up gear that I always use.  I'm always amazed at how the 
cable TV, two way radio and even some HAM installs that I run into don't 
have any weather proofing at all.  Perhaps its because we're sooooo dry out 
here (9" or so or rain per year).

Thanks for all the ideas....

Im going with Male N connectors on the ends that go to the tower and the 
shack....Female N connectors on the splice jumper.  Also lots of tape wrap 
since its going back underground.

Thanks...Rich

For a splice I'd install a male connector on one piece and a female on the 
other.  You get them them in most types such as N, UHF, and I believe 7-16. 
IOW two connectors instead of three which with hard line can save a few 
dollars.
That is the route I've taken with LMR-600.

Just remember that most RTV is not moisture proof. Water proof? Yes, but not 
moisture proof.  Even the stuff theuse to make aquariums is not moisture 
proof.
