There is nothing wrong with using twinlead. It's cheap, light weight and
easy to install.


When wet, it can become much lossier than RG-58. See

Well, that's what you call a definitive answer, hi. I live on the Canadian Wet Coast, near Vancouver --- you could say moisture is sometimes a factor around here ...


Thx and 73 from Canada

Thomas,

Belden made a product called "Shielded Perm-ohm" 300 ohm shielded twin
lead. It apparently still exists, but not with that name. Go to
http://www.fairradio.com/wirean.htm and search for it. The
product is now called "City Color," according to that web page.

Some years ago I used it to pass perfect TV signals through a 15-foot
conduit
out of my attic . (An earlier attempt with regular twinlead was a
disaster.) I
believe the shielded twin lead has slightly less loss than coax.

Roy;

True. Remember I said I don't use the stuff so I forgot that little
tidbit. I also try not to use RG-58 for anything other than a mobile
antenna and I am trying to get away from that also.
