Hi Phil, I just didn't want to be told by someone that discussing hardline
is irrelevant because no one needs to use it. Hardline is also required on
long runs. I was speaking with a friend in Oman on skype yesterday, and he
was in the midst of replacing a 400 foot run of RG213 to 7/8 hardline on his
40 meter circuit, and inch and 5/8 on his 20 meter 6 over 6 stack. I was
incredulous that anyone would use RG213 on such a long run. I heard back
from him today, and he couldn't believe how much better he can hear stations
now that he isn't experiencing great losses in his 213 runs.
I had originally installed half inch Andrew from my shack to the base of my
tower because I had been given 700 feet of brand new hardline. Then, for
some reason that I can no longer recall, I decided that I should replace the
half inch hardline with 7/8 hardline. My run is roughly 100 feet from my
shack to the bottom of my tower, and that 100 foot length of 7/8, + the 7/16
DIN connectors on each end, cost me something like $800, and I couldn't tell
any difference. If the run was for say 900 MHz or higher, there would have
been a substantial improvement, but at frequencies below 30 MHz,it wouldn't
be detectable except by high precision instrumentation.

Alan,
I must be weird but I find feedline discussions as interesting as antennas
and antenna building.
