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

· 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 (Cushcraft 13B2 modified to have triple reflectors)

· 70 cm, 432 MHz, 19 elements: Cushcraft 719B

· 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 (Hy-Gain) HG52SS 52 ft crank-up tilt-over tower is up. I used an RCB-70 Tower Base Assembly and TA-70 Tilt Over Accessory as the tower foundation, and 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.

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