Not to mention, also, that that yagi is tuned to 92.9 MHz (in the FM
BROADCAST BAND)! --Jim NN7K

yes, indeed it is!!

Yes, that will really help. ;-p

I'd add the picture I looked at appeared to have a metal mast
mounting
a vertical oriented beam and my experience at VHF and up is that
hurts
performance.

We modeled the mast in the position it's in,
and changing the length doesn't affect the pattern
significantly.

All the years of building and testing says, extroadinary claims are
simply that. It's interesting to check the CSVHF range tests of
antennas on real antennas seperate from their sometimes fanciful
claims.

I presented the theoretical calculations,
not actual measurements, sure.

Anyone with a VHF anechoic chamber?

Slick
