Here is a couple of pictures of the “business end” of my antenna switch. This was built with  items that I collected at ham fests and a couple of proto boards from Radio Shack. I think I have about $50 in it.

Theoretically, it should be able to handle the legal limit, but I don’t have that kind of power available for testing.  Worked great on all HF bands with 100W key down, though.

Home brewing is fun!
