NOT sturdy. If you're going to use one, it MUST be well guyed, contrary 
to advertising and photos on their website.

A simple solution I used on the house I owned in Chicago were Radio 
Shack tripods and masts designed for holding TV antennas. One at the 
front peak of the house roof and another at the peak of the garage roof 
held up a loaded 80/40 dipole (about 100 ft long, with loading coils, 
purchased from HyPower Antenna Co). Those masts WERE guyed, using #12 
insulated copper, and I loaded one of them as a vertical on 30M and 10M, 
with radials, of course.

Another option worth considering is a multi-band vertical on your roof. 
Antennas like the HyGain AV620 AV640, and AV680, the the Cushcraft R6, 
R8,and R9 are good choices -- they're well designed and don't need 
radials. Lots of ideas in this piece that I wrote last year for National 
Contest Journal. http://k9yc.com/AntennaPlanning.pdf  and the slides for 
a talk I've done at Pacificon and for several ham clubs. It includes 
photos of the TV masts.
