All:
I plan on replacing my HF antenna with an Optibeam model 16-3 Yagi. It's an
interlaced 4/4/8 element Yagi that covers 20/15/10 meters. The antenna weighs
130lbs with a 33 foot boom with a wind rating of 12.7 sq. ft at 75 mph.
I also plan on adding an additional 6M and 2 meter Yagi's above the HF Yagi on
an 18-foot mast. The specs for the 6M / 2M antennas are 30lbs 30ft boom and
16lbs 21 ft boom. Windload is 5 and 2 sq.ft. at 75mph.
The total weight in antennas comes to 176lbs with an estimated wind load of 18
sq.ft.
My tower is the HD555 heavy-duty model made by U.S. Tower. It has an antenna
weight limit of 200 lbs and a wind rating of 23.4 sq.ft at 75mph. The rotator
is the Yaesu 2800.
This setup "should" be within the towers rated limits, but I wanted to run the
numbers by the group since there's a lot of experienced folks on this reflector.
Thanks, Tony -K2MO
