for 



a = -9.2 (Earth edge +0.5 tolerance), 



e = 22.5°, and 



R = 26 in. 

 Then, 



8 = e - a= 31.7° 



and the phase shift is 47.7° at 401.9miz and 55.6° at 468.8MHz. 



A new element is switched in at this point, changing G to -22.5 



and 3 to -13.3°. The phase shift jumps to 8.6° at 401.9MHz and 



10.0° at 468.8MHz. The step change in phase due to switching 



is 39. lo at 401.9MHz and 45.6° at 468.8MHz. This phase step occurs 



once every 75 ys for a spin rate of 100 rpm. Figure B-3 



shows how the peak phase and phase jump varies with a.
