not to see much advantage, but wanted to try the worst case. I was pleasantly
Just to illustrate some tribulations I went through at Cape Hatteras, NC.
First time I tried 2 el. with parasitic reflector on the Ocean side. Problem with
The backup "killer" array was 3 el. on the sand dune with StackMatch. Sucked
major time, best "3 el. non-directional array". Turned out that advertised
performance for using StackMatch for 3el. vertical array is not there, it needs
coax shield going to verticals to be disconnected from the box.
Then I found place on the bay side, with almost no tide. Time to try 4 square.
Another punch was using Comtek box trying to feed elevated vertical dipoles.
Turns out that on 10m Comtek is looking for low impedances to work properly,
so had to go back to slightly elevated 1/4 wave verticals configured as 4
square, worked out fine.
Then I played with 3 el. corner fed Quad on the boat ramp, good complement
for 4 sq. but far from some serious bad arrays that are on the drawing board.
OK on CN8WW (and IG9/IV3TAN 160) records, they are unbeatable until next
