Thanks, but I think you missed that I was asking about a reflector screen with a Gray Hoverman with top & bottom NARODs, and not my MB4.
In the meantime, I was thinking that maybe I could actually manage the colinear rod reflectors of, say, a GH6n3 by building a PVC frame with holes on the insides only to bound copper reflector wires. My only question with this method is whether PVC acts as an insulator or not, so that I can determine what the length of the wires should be.
Back to the MB4:
FYI, it is a 9.0x8.5 mclapp. I would have preferred one of the larger dimensions, but I was limited by the lengths of the coat hangers that I had on-hand.
Today I mounted 6' of PVC to the back of the wooden mast, and properly mounted the reflector screen; next weekend I hope to do a roof test to see what kind of reception I can expect from a discrete mounting location. This thing is now heavy (>20lbs?), mostly due to the addition of short 2x4 lengths to the sides to form both a channel for the PVC and spacers for reflector mounting:
I realized afterwards that I should have sandwiched the reflector between
the 2x4's and the horizontal boards, both because the boards will interfere with the reflection and because the reflector is now close to 6" back from the whiskers instead of the apparently more optimal 4-5"?
