I am using a whip antenna mounted on a metal patio cover. Results are good
on 10 and 12 meters, and contacts have been made down to 40 meters.
(Matches were not obtained on 15 or 30 meters) The whip is 8.5 ft long (a
longer whip is under consideration). It is fed through an antenna tuner
and about 25 feet of RG-58. I'm about to replace that with RG-8.

Any comments on how to hold down feedline losses. One suggestion is to
use two parallel lengths of RG-8 so that half the current runs through
each. Also, site geometry would allow open wire feed.

Possibilities?

As John mentioned, 25 feet of coax is too low of a loss to worry about
especially below 30 Mhz. The other best bet is to use a remote antenna
tuner at the antenna. A longer antenna should work much beter on 80 and 40
meters.
