[TowerTalk] TowerTalk If you had a choice

[David Gilbert]

And yet, incredibly, the Mosley specs for the Pro 57B say it has 8.5 db 
gain over a dipole (dBd) on 20m/17m/15m/12m with only three elements per 
band.   By comparison, Optibeam claims 8.5 dBd for their 5 element 20m 
monobander on a boom twice as long as the Pro 57B.

No way on earth that three elements would be capable of 8.5 dBd, but 
apparently such unfounded claims sell antennas anyway.  I don't dispute 
that the Pro 57B is durable, but that's like bringing a 1950's era 
Schwinn cruiser to a modern bicycle criterium race.
