VHF Yagis for 6m thru 1296 MHz are shown here mounted on a 2 inch OD aluminum mast in the HG52SS cranked up to about 50 feet.

The antennas from bottom to top are:

         6 m, 50 MHz, 5 elements: Cushcraft A505S upgraded to K1WHS design 5 el on 17 foot boom August 2018 (picture far right below)

         2 m, 146 MHz, 4 elements: Vertically Polarized Beam for 2 Meter FM Operation, Unknown Manufacturer

         2 m, 144 MHz, 15 elements: W1JR prototype JR Boomer, a Cushcraft 13B2 modified to have triple reflectors

         222 MHz, 13 elements: Unknown manufacturer, similar to Cushcraft.

         70 cm, 432 MHz, 19 elements: Cushcraft A719B

         33 cm, 902 MHz, 33 loop elements: Microwave Associates

         23 cm, 1296 MHz, 46 loop elements: Microwave Associates


As of early September 2008, just in time for the ARRL Sept VHF QSO Party, the Tristao (Telex Hy-Gain) HG52SS 52 ft crank-up tilt-over tower was up.

I used an RCB-70 Tower Base Assembly and a TA-70 Tilt Over Accessory as the tower foundation. A TB-2 Thrust Bearing is used to mount the antenna mast on the tower.

A Yaesu G-600RC rotator is used to point the antennas to the desired azimuth, this was upgraded to a Yaesu G-1000 DXA in August 2018 to achieve 450 degree rotation to avoid a dead spot.


My thanks to VO1HP for sharing his ideas on how to put up an HG52SS tower.
