As I consider the materials required to replace my 30 year old tower, rotor, antenna and cables, I have several like new runs on LDF4-50A terminated with N-male which could run from my ground window
Gary Andrew makes UHF female connectors for 1/2 LDF. If you use male male jumpers at the top and bottom you can avoid the adapter issues. The old part number is L44U...there may be a new number in re
Greetings, From my experience, the use of Hardline on HF does not affect loss very much. I've seen more problems with poor connector attachment or lightning pinholes that allow water to seep in. No m

I'd use the LDF4-50 with the N type connectors. From there around the rotor I use good quality RG-8 or RG-213 with a N connector on one end and a UHF on the other. At the window I'd change that to a
after all I have read on coaxial cable, I would choose the LMR-400. the difference in signal loss at such a short run would not be noticeable to the ear. jack ak7o --Original Message-- From: GARY HUB

It looks like maybe the LMR-400 has two tenths of a deciBel more loss below 30 MHz, IF everything is perfect with the Heliax connectors and the rotor jumper. The 75 feet of LMR-400 is a lot easier to
But is one going to operate at 30 MHz frequently? Doubtful. Of course loss decreases with frequency. Anytime I have a feedline total loss less than 1 dB measured {key point is measured not "book" num
The assumption here was that he already owned the Heliax. If I were to buy new coax for my tower it would be just what I bought last time..Times Microwave LMR-600. I have 6 150' runs out and up the 6
I'd worry more about connector assemblies and water tightness. Ron - N5QV But is one going to operate at 30 MHz frequently? Doubtful. Of course loss decreases with frequency. Anytime I have a fe
Hi Gary I would use the 1/2" Heliax. I use both and the outer jacket of the Heliax is superior to the LMR for both water and sun. It also has lower loss. I would use LMR400 UF or similar for the rota
