Hello David
Sounds more like improvised Post War tent poles.
I'm no expert but I've not heard of wooden aeriel masts........... yet. Tent poles yes.
The diagram you refer too mentions 'D' Rods which were about 3' in length, 7/8 diameter, threaded male/female. 'D' Rods were originally British and used to make up horizontal aerials and vertical antennae.
The diagram explains it so I won't reiterate it here.
This is a nearly complete 'D' Rod aerial set.
The actual mast kit. Many of the items were still in their original wrappings or what is left of them.
Guys, pin bag and pins.
Misc parts in boxes, guys, ground spike and the insulated base mount.
An F Rod adaptor; this is not the one included with the kit, the one in the kit has the spring clamp at the top and a wing nut on the bottom both are threaded for the D Rod. This one can not be mounted directly above a stay plate as it would interfer with tightening the clamp. F rods were then added to make a 34' antennae.
The Canadians developed the 34' telescoping antennae and 20' mast to replace the D Rod set-up. circa 1944.
20' mast on the left, 34' antennae on right.
