Do not rely on HFTA for this sort of decision unless your terrain is
really complex, and then only after doing modeling with NEC2 or EZNEC.
The HFTA model is very simplified and, as Billy pointed out, gets iffy
with closer spacing. To see an extreme case, try 2 x 5 element HF yagis
2 meters apart.

Hello
Wich is the ideal space between two 15 mts monobanders on 44ft boom?
HFTA tell me that 36/30 mts is better than 36/18 mts or 36/20 mts but I
think 6 mts space between the two antennas is too close.
