For my use I would consider a stack of 6's to be too narrow for contesting from the northeast. Up here a stack of 4's is probably better to cover more of Europe at o; /archives//html/Towertalk/2002-11/msg00334.html (9,657 bytes)

I expect everyone's idea of optimum depends on their own persepective. point to The 6L models on 0.75 WL booms in W2PV's Yagi Design Book show a -3 dB; /archives//html/Towertalk/2002-11/msg00335.html (10,644 bytes)

Certainly your coverage of Europe must be less than that. KK9A Optimu; /archives//html/Towertalk/2002-11/msg00336.html (10,593 bytes)

7. [Towertalk] OPTIMIZED ANTENNA SYSTEM (score: 1): Author: k1ttt@arrl.net (David Robbins); Date: Fri, 15 Nov 2002 13:27:46 -0000; 50-60 degrees would be about right. I'm kind of surprised the pv design shows that beamwidth though I would expect it to be narrower.
