I have approx. a 160' run of 3/4 CATV going to the tower. my question is =
this, the overall length of the run, should that include going from the =
back of the amplifier to the antenna? I have a 6' piece of 50 ohm going =
to my 75 hardline then back to 50 ohm rg213 to the th6 stack, approx 33' =
each.......I never once measured anything when I put this all =
together....I do get some off the wall swr readings...at the antennas it =
all looks good but once you get inside...yuk.......does the 50 ohm to 75 =
ohm back to 50ohm cause problems.....should i get rid of the CATV and =
get some 9913 or something similar for the whole thing?
Any thoughts?
