Hi Nat,
I've heard it many, many times where a small station on the East Coast is
giving a big signal report to a DX station that can't be heard at all out
here. If the guy is 20 over 9 on the Coast and inaudible here, what kind of
an antenna do I put up that has 30 db gain? I think your estimate of stack
gain over a dipole is pretty optimistic. There's a lot more to this than
apparent gain figures of different antennas.
I also do a lot of DXing. I've sat in pileups and listened to East Coast
MOBILES waltz right through.
Look at the published list of signal reports from Europe after a DX contest.
One of the biggest stations around here, W0AIH, is always way down the list
in spite of the fact that they have big stacks at height.
I'm afraid we're going to be in disagreement over this one, Nat. It's a
different world out here and you can't compenstate for it with bigger
antennas.
