[amsat-bb] Crossbooms ... my pennyworth.

Hello All,
             Stating the obvious ... if one mounts the aerials as per a Wimo 
satellite X-Quad ...
(using counterweights if necessary) ... one eliminates the crossboom problem 

I've compared this kind of system against my more usual 2 x 6 + 2 x 6 
homebrew array for 2m and 70cm ... (each aerial  mounted at 45 degrees in 
relation the other) ... and correctly phased for switchable CP.

In my humble opinion, on LEO's the squint experienced just doesn't warrant 
the effort of being (theoretically) correct. It did make a 'slight' 
difference on AO-10 and AO-13 (HEO's) but still hardly worth the effort of 
being "technically correct".

Others may have a different opinion ... which of course, they have evey 
right to have.

I respect that.

73 John.
