A Homebrew Roof Mount for a Small Transmitting Loop


I had a good Small Transmitting Loop (STL) in my backyard for almost two years and it worked well enough. I finally decided I was tired of mowing around it and telling the kids to keep away from it, and I knew that the shed rooftop would be a good location for it.

Finished assembly:

Assembly in the garage:

Shoring up the shed roof. I decided to add a couple rafters and some bracing. The legs will be secured using threaded rod, a standard recommendation in the ARRL antenna book.

Mounting. There's always some difficultly along the way, which for this project was an 1/8" drill bit broken off into the pressure treated wood. I was able to come back and add the remaining rod later.
