The array I used to work my first EME (150 watts)
(W5UN of course). 48 el on 144 & 96 el on 432.
Used mostly for satellite.

This is my homebrew Preamp/Relay box for the dual
band EME array.
This is the antenna rebuilt after the January '99 windstorm:
This antenna was replaced in March '99 by the 16 X 12
array for 432 MHz only.

Yaesu FT-767 with 50/144/432 MHz module |
|
16 Yagi antennas of the 2.2 wavelength NBS design |
|
