I have used them a lot, pound a long iron pipe into the ground, and use U bolts to hold the mast to the pipe. Some sort of anchor to the side of the house and you are good to go. I put a pulley at the top so it can stay up. They rust badly over time, and from a steady sideways load assume a ( over time.
After 10 years it was still up but looking real nasty and I had rust stains on the side of the house. It used to hold one end of the 80 meter dipole up, and I took it all down and tossed it all in the trash. I need to put up an 80 meter dipole, but will use trees to hold it up. I thought about something really thin and light to hold the center of the 40 meter dipole up, but it would need to be real thin else the xyl will have a fit...
