Works good but I haven't run into any mechanical problems that others
have (easily solved by using bolts thru the boom-to-element clamps and more
rivets on the elements).
The only thing I don't like about the 40M linear loading scheme is that
each element needs to be tuned independently in the air; it cannot be assumed
that just measuring it will give you the resonate freqs you need for optimal
performance. This is in contrast to the Cushcrafts that you can
'set-and-forget'.
The F12 antennas are generally lighter and exert less mast torque than
comparable antennas.
IMO electrically and mechanically F12 antennas are quite good and
superior in some respects. Some design/performance inferences can be made
from their triband antennas which placed highly in our on-the-air tribander
comparison report plus the gain figures in their brochure are realistic.
Monoband antennas are easy to design these days with computer modeling
programs; the trick here is how to interlace them for minimal problems. F12
seems to have this under control.
