Hello damtanmann: Here is the address from CB Tricks on the Super Scanner manual:

The manual doesn't show the arm lengths, but the photo in the earlier posting here shows a Super Scanner Antenna, scaling the right hand element as being 9 Ft long it looks like the arms are about 2.5 Ft long. The manual calls out the coax length to use. At 100 watts I am sure any 10 Amp relay will work.
Suggest you get it all together and just prop it up against a shed or fence to verify the relay in the antenna box is working.
Good luck
