I have adapted parts of some of w2ihy's stuff to do similar things. I have
also used Mackie and Behringer mix
Heres a quick rule of thumb as far as cable bend radius.
The Electronic Industries Association / Telecommunications Industries
Association specify that the worst-case cable radius of any cable that is
compliant, is 20x the outer jacket diameter for any cable under pulling
strain. This is used
Which would be strike three because the cable I replaced was
made/sold at/by Times Microwave as a factory-made jumper.

Hi Scott,
If you saw a previous post... I mention the soft flexible coax
line foam vs the more firm or hard foam found in rigid coax...
aka hardline.
There are bend radius specs given for most good/higher end

Jim,
We at Repeater-Builder (the company) have many complete, used GE mastrII PA's
at reasonable prices. What band and what power are you looking for??

Hello All
How about 1/4 inch Andrew Superflex hardline for fixed jumper service in a
repeater system?
This cable has a foam dielectric-is there a center conductor migration
problem and if so at less than what bend radius?
Many thanks---
Scott, N6NXI
Sometimes it's the connectors. LMR-400 can be problematic on a duplexed
system, but poorly installed connectors can also be the problem.

I wanted to let everyone know that I have successfully tied in my Sony laptop

first, but after I found the screen that had the repeater freq's
I thought the big problem with LMR400 was when used as
the feedline up a tower to a repeater antenna. The
temperature changes were causing expansion and
contraction of the various layers, which rubbed on
each other, causing noise.
I would not expect that inside a building, unless of

I think it was prolly the "million diode marching band" generating broad
spectrum noise...
I have seen exactly the same thing here, and they were in climate controlled
buildings.

Skipp,
Interesting account! Will you be performing an autopsy to determine the
exact cause of failure? I'm curious about how a bad cable on the TX side
caused the RX to be degraded.

Doug,
About the best answer is, "It depends."
In the case of the TX cable, not only does the optimum length depend upon
the frequency, but it also needs to be based upon the design of the cavity
and the transmitter. That's because there are three parts of that cable:
The length of the coupling l

What kind of transmitter is this ? pre or de emphsised audio type of
controller ? 90% of the time this flat or distorted sounding audio is
usally a loading effect into the audio circuit of the transmitter.

Hello,
Seeking some guidance re the correct length of cable to use between
cavity and transmitter, cavity and receiver on a dual antenna system.

Is it 1/4 wave or are multiples of 1/4 wave acceptable?
