Yes, he spent a few bucks on this project!

my question is Why ?
1500W * 100 (20db gain)= 20,000W ERP
Gak! typo....
1500W * 100 (20db gain)= 150,000W ERP not allowing for feed line loss
and I saw heliax there so it should be low. Even if it's off by 3db
75,000 is a huge number.

With that you can work backscatter and really weak signals that would
be missed with lesser antenna. Propagation is not a switch it's
more like sahes of gray from nne at all to weak.
I mean he has the ability to do it obviously, and the technical to do it
yes. But Why. Is it that much more over a standard 4 elem steppir
at say 70 FT. It wont open propagation that isn't there ?
Yes, much more and with narrow beamwidth other noises are less an
issue.
People have ben doing this for years at VHF/UHF and those that do
are heard, seriously heard.
Must have cost a mint..
