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^)
