[TowerTalk] Combination 40-30M Antenna

[ABowenN4OO]

I am looking for a combination 40-30M, 2 element rotary beam.

So far I have found Optibeam, Force 12 and M Squared.

The Force 12, 2 el X 2 el, linear loaded appears to be the least 
expensive and the best potential performance for the money. The Opti, 
being imported, is almost twice the cost of the F 12, but appears to 
be well engineered. The M Squared is a log type antenna and much 
larger than I want to put on the tower.

Are there any others that I should consider?
