Nobody seems to talk about the wave angle of the beverage
main lobe, at least I havenīt seen anything.
Seems to me that anything much shorther then 4 wl doesnīt
work. If you check Misek's book you can see that you need
about 4 wl for 25-30 deg waveangle and anything higher than
that is useless.
In any case I have tried many many beverages and for me they
donīt perform untill they reach 1000 ft approx, all this work was
done on 80 meters, figure same would apply on 160.

PS: This 2wl stuff below I donīt understand. IMHO the waveangle
is the far too high to receive the DX. Sure the wire will RX a lot
of signals but Iīm looking for DX and where Iīm at in the aurora
zone the lower angle I can produce the better. Any more idéas?
