Brian,

Yep, a missing dual BI & BIII dipole (or perhaps just a BI dipole with the 'director' that is second from the back actually being a BIII resonator) on the lower one would explain many things!

That is, 3 BIII directors, a resonator BIII element and a Band III reflector on the same boom as a BI dipole and BI reflector.

Indeed at a distance of 50 air miles, both Pontop Pike and Burnhope would be running out of microvolts at that location. Out of interest, was the location shadowed towards the TXs ?
