I have a pair of OptiBeam OB2-40 beams at 75' and 150' high. For their size
they work very well. The loading coils are massive and in my opinion a
better shortening method than linear loading. The construction is excellent
and OptiBeam's customer service is fantastic. BTW, I made a lot of QSOs
using single OB2-40 at P40A. I am sure that the OB4-40 is a great
performer.

Looking for any feedback on either of the OB4-40 or the 40M4LLDD. If you
were
to decide to install one vs the other....Why and if you have either antenna
what would your pros / cons be?
Thanks...
