Hello Dave:

I am using two four squares for 80 meters. They are spaced 5/8 wavelength
apart (broadside to Europe). There is 3 dB additional gain with two 4
squares compared to one. They are each fed with 3/4 wavelength of 50 ohm
cable. The 25 ohm junction feedpoint is raised to 50 ohms with a 1/4
wavelength section of RG-83 (35 ohms) coaxial cable.

Performance is outstanding.

73!

Hi all - does anyone know of a site that will give me info on phasing two
4sq arrays and what gain I might expect over a single 4 sq - many thanks
