QFH Antenna and 72ohm TV Coax
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 specified 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. Lee......de G6ZSG..... |
