I recently installed a makeshift antenna on my roof similar to the
"temporary" one I have been using for a couple of years, but its performance
is severely degraded (not quite as good as my whip antenna, by itself). Now
I think I have found the problem, but want to check with those on the group
to confirm my suspicions. I used RG59 coax in combination with 300-ohm/50
ohm baluns, but now find a source of information that says RG59 is 75-ohm,
not 52 ohm like the guy at the parts depot told me. Which do I believe?
The (young) guy who cut the cable for me, or the book on RF design that some
people says is full of mistakes? What is the actual impedance of RG59 coax?

Thanks for any help...
