John,

Nice to see one being re-erected.

A question : Are you certain that the aerial make is Telecraft and not Telerection?

I ask because I had a channel B2 only version of this X design and I'm 99% certain mine was a was Telerection. Mine was a director -dipole type of X (like yours), with the connections to the Band I part via terminals which are the inside of the dipole holder that pushes into the boom. I found that the connections were open circuit to the dipole elements. Clearly the elements were threaded and screwed into the holder. They were corroded fast and could not be shifted. So "an interesting aerial to look at but for recommissioning purposes, not a lot of use".

I see that you have a folded dipole for Band III, I trust you have checked that for continuity. Are you using a diplexer to combine the separate BI and BIII downleads?
