[TowerTalk] Multi-band dipoles

[David Gilbert]

By all accounts I've read, the B&W folded dipole is indeed broadband.  
Since it has a relatively small fixed "tuning network", that can only 
mean it has significant loss relative to a normal dipole.  Estimates 
I've read vary between one and two S-units.

By all accounts I've read, it is a "quiet" antenna on receive.  Since 
noise rejection can only come from pattern or polarity discrimination 
and the B&W antenna has no more of either of those than does a standard 
dipole, that again means it has significant loss.  The antenna is 
probably just as quiet on the other end as it is on yours.
