I`m building a QFH NOAA weathersat antenna and wish to use low loss t/v coax
which is
72ohm; but is more manageable and less lossy at VHF than the 50ohm RG58

over a 100ft run!.... ( RF pre-amps aint cheap! ).......

What are the pros and cons... can i use CT100 72/75ohm..... i believe i can
but, will the impedence affect
the 4 turn choke ????...

Thanks.

It will work perfectly, because the TV coax is good HF quality.

Why do you use a 4 turn choke?
