Bob2. Retired Nuclear Instrumentation System Engineer (formerly with Exelon Quad Cities Nuclear Power Station and TVA Browns Ferry).
Interested in VHF/UHF/SHF weak signal work and contesting. Like to play on WSJT and anything to do with 6M.

Top picture is the primary VHF/UHF tower.  80' stationary with 50' K0XG rotating top.  Pairs of long boom 6M through 3456 MHz antennas.  6M antennas are on 50' booms.

 

  

The 4 Bay Array completed May of 2013. 8x7el. Each Bay has 2 antennas stacked at 1/2WL ~10' (to emulate the gain of a longer boom antenna ~13dbd). Bottom Bay starting at 1WL above ground (for high angle)then 1.5WL spacing (20, 50, 80, 110 feet to the center of each bay). The 4 bays are selectable in any combination to take advantage of different wave arrival angles. Total gain with all bays selected is about 19dbd at a 3.5 degree radiation angle.

Top of the 160' K0XG Rotating Tower showing the top bay of the 6M array but with the June 2014 addition of a KT-34XA 6el Tribander and a HyGain Explorer Shorty 40.  Both antennas were in the garage for almost 20 years and put up for the ARRL Centennial QSO Party to operate as W1AW/9 from Illinois.  A homebrew 4 EL 10M at 35 feet is not shown.  

 

The horizon from the lower 11el 6M antenna's perspective at 105'.  6M array is to the right.  Looks pretty much the same 360 degrees around.
