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?
