Re post no. 105:

The top aerial looks like a single 6 element Belling & Lee that has lost its folded dipole. The evidence for this conjecture is:

1) the close spacing of the 4 directors (typical B & L);
2) the fact that it was a 6 element design (a common B & L design - many competitors used 5 or 8);
3) the boom diameter is 3/4 inch (the design choice for all B & L Band III aerials);
4) the shape of junction box cover. If it were a B & L then this cover would be a pale blue colour made of flexible rubber.

Having said that I'm puzzled as to the lower aerial (clearly a combined BI & BIII design) which does not look like part of B & L double at all (no phasing bars for one thing). Moreover no trace of a junction box on it, and the BI element holder looking like a standard but non-dipole, element holder. Also its boom diameter is 1 inch.
