Larry:

I bought one of those when they first appeared, and put it up. The traps lasted only a few months, before they sucked
water and detuned. I am still using that antenna with the replacement solid traps they provided as warranty
replacement. I'll bet Leo really lost big time on that first design.

Unfortunately, I cannot find either the original instructions, nor the later dimensions which came with the replacement
traps, but bottom line is that those black traps were a problem waiting to happen.

Came across a vintage Hy-gain beam in excellent condition with the four inch
diameter black traps. I think this beam is from the late 50's. Need
element length and spacing dimensions. Missing the gamma matching sections
so will need configuration for the matching the single length driven
element. Would be great to get a copy of the assembly and installation
instructions.

Any help would be appreciated.
