Spring / Summer backyard tower project

Thanks John I appreciate your offer.  I have discovered an out of band orphan spot that might be trying to impersonate the 20 Metre band.  I have discovered 1.28:1 @ 13.290 MHz.  The 20 Metre capacity hat has four 15" radials.  Hy-Gain claims the antenna is tuned at the top of all the bands and you tune it down to the desired frequency by trimming the radials.  Since I want to go up, not down, it seems to me I might want to add longer radials.

The antenna came with two spare 40" radials for people to start over if they trimmed too much.  Maybe I could try these to bring 13.290 MHz up to my target 14.150 MHz.
