[FoxHunt] Turnstile antennas for 2M

[bob]

No not true or very true. The Yagi and most directional antennas are 
directional in both planes about the same. The ground interaction causes 
vertical lobes in the elevation plane for both horizontal and vertical 
polarizations.  It does rule out using a lot of direction finding 
techniques such as dopplers and LPers as they are most difficult to get 
going H-Pol.

Well it is probably a good thing in that it will spurn the genuises out 
there to come up with a automated direction finder for H-Pol to replace 
the doppler and adcock, TDA, BMG and other V-pol techniques.
