[TowerTalk] HF Vee Beam Experience?

[jeremy-ca]

Back before computers told us that everything we did was wrong I put up a 
Vee that was 2 1/2 wave per leg on 80M and 5 on 40. Height was only 60' 
which was all I could do with 8 scrap telephone poles and 2x6 extensions. It 
was strictly to work the South Pacific on greyline in contests. There was no 
5BDXCC back then.
 I found a pair of 100 Ohm 200W glass resistors at a fleamarket and used 4 
150W light bulbs in series/parallel on each side as well. Ground was in the 
Exeter River at the rear of the 12 acres I had back then. A Johnson KW 
Matchbox loaded it perfectly and it worked as expected and outperformed 
inverted Vees at 90'. Power was from a NCL-2000.
