A deep null is necessary only if there is a very strong noise in the null
area.
I find the Echelon arrangement not especially helpful because there is
little QRN at ~235 degrees.
Instead, I pick a element length and spacing that has very deep nulls
towards Florida. When I watch the lightning maps, most frequently storms
are over Florida. The closer Florida storms are also very much louder here
than anything from Central America, plus it helps reduce QRM from a SSB net.
