[TowerTalk] Trap Identification Hepl Please

[Wilson]

I have five nice traps, who knows where they came from or what happened to the sixth.
They are labeled Director, Reflector, and Radiator.
I never saw anything called radiator, so it’s likely an ID help.
You can see them in my Dropbox:  https://www.dropbox.com/s/1u12u0f9fa3690b/Traps.JPG?dl=0

Can anyone tell me what these were for?
Was it a two band beam, since there may have been only six?
