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?

Years ago I had put up a similar antenna to be able to get onto the
local 10M net. I then as you have tried to tune it up on other bands
after upgrading from Tech+ to General and got similar results to what
you have discribed. Changing the radiator to 5/8 wl on 10M improved
operation of the antenna not so noticably on 10M as it did the other
bands. Good luck, have fun and learn.
