shows a single Polyphaser, bulkhead mounted. They also have a right
angle bracket so may be surface mounted on a flat Aluminum or Copper plate.
In my case I used a 1/4" thick Aluminum plate, but the above box is
getting replaced with one much larger with an internal plate of at least
12 X 12", or maybe 16 X 16"
If the polyphasers are bulk head mount only just mount a piece of 1.5" X
1/8" Aluminum angle on the back plate and drill it out for the polyphasers.
