Bob,
A PL259 or SO239, a good one, is good to 500 Mhz although at UHF, 440, I would recommend N connectors as you suggested.
One problem with UHF connectors, PL259, etc, so many are made for CB. The cheap 10/$10. Good for HF, but that is about it. Guess ok on 6. Motorola and GE used UHF connectors for VHF and UHF for years, but they used the good ones.
An Anphenol is good. Just another case one gets what one pays for, hi. 73, ron, n9ee/r Ron Wright, N9EE 727-376-6575 MICRO COMPUTER CONCEPTS Owner 146.64 repeater Tampa Bay, FL No tone, all are welcome. On Sun, May 11, 2008 at 10:43 PM, [EMAIL PROTECTED] wrote: At 5/11/2008 14:39, you wrote:
I have followed with interest the thread treating feed line to use to connect repeater/duplexer/ antenna, and I think I should replace the cables that are now in use on my 2-m repeater. But now the repeater TX and RX and a remote base use short cables to a feedthrough on the top of the cabinet. There are 90 degree elbows on the feedthroughs. Would it be better to eliminate these feedthroughs and elbows by just cutting a hole in the cabinet and routing the cables directly to the radios? What is common practice?
Feedthroughs are always better, provided they're N connectors. Among other things, they help keep the rodents out of the cabinet. N elbows are good up to a least a couple GHz, so they should work fine @ 440 & lower. SO-239 feedthroughs are all bad @ 440, as are PL-259 elbows. I even had one cause desense @ 146 MHz (nothing but a dummy load on the other side; remove the
elbow, desense gone!). Bob NO6B
