[Antennas] BWD-90

[dtx]

http://www.cebik.com/wire/t2fd.html will provide some interesting 
reading while you wait.  Note you can make some interesting variations 
and get fairly nice SWR and reasonable patterns, but notice some of the 
gains for those patterns are -4.4 and -3.06 dbi, which is down approx 
2.5 db from broadside to a dipole at 1/2 wl elevation.  Not that many of 
us can get our dipoles a half wl up on 80M<G>
