[Antennas] WxAU Balun

[John Hensley]

I recently took down a trap dipole which had been up for a couple of decades.  Cleaning up the balun which is also serving as a "T" shaped center support, I realized I had no idea how to check it.
I would enjoy hearing from anyone who has messed with thesethings.  I have no idea what is inside.  The caps are black, thebody is gray PVC about 1.5" diameter.  Grounding strap runsdown the side.  I used to see these at every hamfest I went to.
Before I forget the performance was lousy but then again, Iwinged it.
