[TowerTalk] NVIS

[dj7ww at t-online.de]

I had very good results in our local (within Germany) sprint contest on 40m
with the Jamaica antenna where only high angle radition is necessary and
supressed interference from Europe.

Well part of the discussion has been why not 1/4 wave high since you 
gain some lower angle performance without losing any high angle. If one 
thinks about it in terms of low noise *receive* and doesn't need the 
lower angle - that's why.
