Topband: High noise with Rx antennae

[Gary Smith]

yes it is, although the quietest directions are to the N, NE & NW 
which would make those directions the worst if it were the rail 
lines.

I'm finding that the Rx triangle has more noise than the 160 Inv-V 
and that doesn't make sense to me yet. I don't use a pre on the low 
bands & sometimes use an attenuator.
