Hi Frank,
4.3-10 can't be so expensive if compare new to new. E.g. 7/16 to 4.3-10
"brand" adapter bulk price is 10-15% higher than N to 7/16, also price
of few meters prefabricated "jumper cables" with 4.3-10 vs 7/16 differs
in 10-15%.
I hope it revers soon as and also cellular antenna life spa

The only issue to think about it carefully is the power rating of
N-connectors (even PTFE).
These connectors are not designed and dedicated for high power and as

I see ZL3IX and N6TR both on TB in K1N clublog. All others too probably.
You need to restart page or something.

I hope they will find that part of log till tomorow opening..

ZL3IX provided measurements for "crosstalk" between pairs - ir was in 50dB
range for CAT5E he had for same lenght.

Hello,
I used not shielded CAT6 UTP, 24AWG, Greg measured also not shielded
but CAT5 UTP. Impedance is 100 Ohm according all CAT5/6/7 specifications.
Simple 4 : 3 transformers (or better to say BalUns in this case) on our
"usual" mix 73 binocles were used on every pair. I think good
for both 50 a
it in
autumn.
"Worked fine" is not very scientific evalutation, but Greg ZL3IX helped to
decide with something real - Thank you Greg.
See his message with measurements below. CAT6 is better variation of CAT5,
so I had less loss and better crasstalk.

Hi,
Is it worth trying to use outdoor CAT5 to feed reversible Beverage?
There are 4 twisted pairs inside, paralleling 2 for both directions will
give something close to 50 or 75 ohms.
Any idea what is coupling between pairs? Any other risks?
