Yeah this will sure prove to be interesting. I'll probably be using 1/2" copper pipe for the elements, and will go with the 3 element design. I don't think that adding extra directors will really improve my gain all that much on VHF.
I am familiar with the ZNY stations in the area. I can pick up Matawan sector controllers quite clearly with a discone antenna in the attic! The milair around here can get interesting too with McGuire and ACY in the vicinity, but right now I am especially interested in tower communication, being that I just recently soloed in a controlled field for my private license.
Anyway, thanks for the inspiration. I think I’ll definitely go forward with this project now.
