Have a Yaesu G450 rotator, pole mounted. (Not tower mounted, no thrust bearing) . Have the following three yagis on a 7 foot aluminum mast in the top of the rotator, all horizontal. 33" between the 6 meter and 70cm (440) and then 4 ft between 70cm to 2 meter at the top Bottom 6M CA-52HB4 11 ft boom , 0.62 sq ft wind, weight 4.5 lb (just above rotator) Middle 440 M2 432-6W 15 ft boom, 0.85 sq ft wind, weight 5 lbs (middle) Top 2M M2 2m-12 20 ft boom, 1.5 sq ft wind, weight 8 lbs (at the top of mast) ---total wind is 3 sq ft , 17-20 lbs of antenna and coax Description for the G450 says "perfect for small HF beams, VHF /UHF antennas up to about 10 sq. ft. of tower-mounted wind load. A lesser wind load of about 5 sq. ft. can be handled when mounting the G-450ADC on top of a mast <---and this is how i'm set up Thinking about adding a 220 beam, not a huge one. This one, MSQ-22210EZ , 10 ft boom , 0.75 sq ft wind , 4 lbs . Does anyone have a setup like this, using a G450 rotator ? To do this, i'd have to replace my 7 ft mast with around a 10 foot mast . Yes, it's semi light, 6061 aluminum but ...10 ft is alot of leverage ! Anyone running something like this ? Do i need to move up to the heavier G800 rotator ? My other option is weld up a pipe bracket that mounts to my mast below the rotator, goes up around it and allows me to mount a thrust bearing a few feet above the rotator. Fabrication and the aluminum welding is not a prob for me. Just curious if I need to do any of this, or will the G450 do it just fine ? If i keep the 7 ft mast and "squeeze all 4 antennas in, they will really be encroaching into each others aperature and collecting area . Am i overthinking this ? Please don't clog the responses with "just get another tower" or blind conjecture. If you are familiar with this kind of thing, I appreciate an educated guess ! note: I have them mounted like this (6/70cm/2m) according to a pdf from directivesystems.com on stacking dissimilar yagi's.
