radio1,
what I'm seeing so far is that it's not a Balun (Balanced to Unbalanced), as the lead-in is twisted wire and the antenna is a dipole that MAY be fed slightly off center. There seems to be a fixed tuning circuit for each leg, but it's going to take me a while to pick this tar-baby apart. The tuning coils are made from the same stuff the RF and IF coils are made of, so they break easy!

Yes, I think lightning would take this out quickly.
