Bill, W0ZV, asked me to post a description of my antenna farm that appeared
on the cover of CQ Magazine's Feb issue.
I am flattered that CQ published it!
I live 30 miles Northeast of downtown Phoenix on 2 1/2 acres of desert land.
If any of you have heard of the Boulders resort, I am just 3 miles from it.
The picture is looking toward the Southwest. There are 4 towers, 3 are 100
feet tall and 1 is a 50 ft. crankup.
The front tall tower (right) has 4/4/4/4 on 15 meters (20,52,84 and 116
ft.). The bottom 3 are fixed EU. At 102 ft is a 2 el Force 12 80m beam.
There is an 11 el 6m beam on a Tic rotating ring at 60 ft.
The 2nd tower (left front) has 4/4/4/4 on 10m (20,44,68,92 ft.) all fixed on
Asia. There is a 6 el 20 at 60 feet on a Tic rotating ring and another 6 el
20 at 102ft. A 3 el KLM 30m beam rests on the mast at 118 ft.
The 3rd tall tower (center) has a 4 el 40m M2 at 102 ft. and 7/7/7/7 on 10m
(20,52,84,116 ft)..with the bottom 3 fixed on EU. There is also 6/6 KLM 6
el 15m beams fixed on Asia at 40 and 70 ft.
In back, (just to the left of the first tower) is the crankup. It has a C3
tribander at about 60ft., a 4 el 17 Force 12 at 54 ft. and a 6 el 12m DX
Eng.) at 48 ft.
Intermixed between the 3 big towers is a 4 square 80m vertical array. They
are shortened Force 12 verticals elevated 10ft on a section of Rohn 25.
Each has 4 elevated radials. I use a quarter wave sloper for 160m off one
tower with the top at 95ft. I also have an 80/160 sloping dipole facing SW
off another tower at 95ft.
Things are a little crowded on 2 1/2 acres. The big towers are about 75 ft.
apart on an L shape, but everything works well. I have not tried a multi
single yet, but plan too in the future.
The rigs are a FT1000 MP and a TS 930s. Amps are an Alpha 86 and Alpha 76CA.
I have 5 beverages spread out (across the neighboring 2 1/2 vacant acres)
which run anywhere from 550 to 650 ft.
I have not tried to shunt feed the 2 Saguaro cactus.
CU on the bands.
