[TowerTalk] add a 3rd el to 40-2cd

[kostas sv1dpi]

In my club we have a Cushcraft 40-2cd antenna. We are very satisfied 
with this antenna. Recently, one of our members, donated us a second 
40-2cd. We have not a tall tower to put them in phase (the antenna now 
is at 22m-72ft). We made a thought to shrink a little the reflector of 
the 2nd antenna and use it as director in a 3el configuration. Do you 
think that it will work? Can anyone to make a model and tell me what is 
the new length of the boom and in what position we need to put the 
elements to have 50 Ohms and finally which is the gain?
