Topband: Phased staggered beverages

[donovanf at erols.com]

Hi Dave, 


270 foot spacing is a good choice only if you're trying to eliminate 
QRN from local RFI sources not propagating via the ionosphere. 


Otherwise 350 foot spacing is optimum for suppressing QRM/QRN 
arriving via the ionosphere

I think the spacing is a bit wide try something more on the order of 
250-270' ( goes through the middle of the house right ....8^)

To do that, one of the 2 beverages will be 110’ in front of the other due to the lot-line orientation. Regardless of the phasing I’m modeling, the side and back lobes are not to my liking. Is the 110’ forward stagger too far? I can get a single 600’ beverage to Eu which has a marginally worse RDF (0.35 less) than the not-perfect-staggered-pair but is much simpler and takes up less land.
