[TowerTalk] 75m wire beam

[K4SAV]

It should work, but remember you have the same challenges making this 
work correctly as you do for any other beam. It will have a narrow 
bandwidth.  Move a little off frequency and the beam direction will 
probably reverse, become bi-directional, or the gain simply disappear. 
Because of the low height, the take-off angle will be higher than 
desired. It should offer some gain, but not as much as you would like 
because of the low height. But it doesn't sound like a lot of trouble, 
so give it a try. If you have some software to model this, it would be 
helpful.
