I am planning a tower installation using 85 ft of AB-105 guyed at 35 ft
and 75 ft supporting a 4 el Steppir (32 ft boom and approx. 10 sq ft wind
load) at about a foot above the top of the tower and a Cushcraft XM-240 or
JK Antennas 3040 (boom length in range of 18 ft and wind load between 5.5
and 9 sq ft.) about 12 ft above the lower antenna. A 22 ft, 3" chrome-moly
mast with a 3/16" or 1/4" wall will be used to support the antennas.
I am planning on using an M2 Orion 2800 mounted on a shelf about 5-6 ft
below the top of the tower and two TB-4 thrust bearings, one at the top of
the tower and one 3 ft down.
If anyone has experience using the M2 Orion 2800 Rotator and TB-4 thrust
bearings and antennas with a total wind load in the range of 15-18 sq ft, I
would appreciate hearing from you via the reflector.
Thanks in advance,
