Luftwaffe Antenna Feed?
I was in France last week and took the opportunity to visit the old Luftwaffe KGr100 base at Vannes-Meucon airfield whilst passing through the area.
There are a few substantial concrete buildings left and a few hangars from the German occupation. On one building this caught my eye. It is about 9" square. Could it be an antenna feed plate? Martin G4NCE |

Re: Luftwaffe Antenna Feed?
I'd have expected a large central hole for a glass or glazed ceramic insulating bush.
Ironically, I was at a friend's last week and he was machining-up an HF antenna feedthrough mounting to replace a missing one in a Dakota which once dropped parachutists and stuff over such places: "Night Fright" which is being restored to fly again. The actual plane his father flew back in the day! They hope to fly it to a D-Day remembrance event in the next year or so. Shame Britain doesn't do /AM amateur radio licences. David

Re: Luftwaffe Antenna Feed?
My French is a bit rusty - as were four brackets spaced out on the roof which I spotted on a previous visit, which looked they they may have once held poles which could be raised and lowered.
I agree about a glass insulator. However, with what looks like an insulated plate and a brass thread and nut, the only other thing I could think it could be used for is a single HT / EHT feed? I will do a bit of further research and see if I can turn anything up. All the best, Martin G4NCE |

Re: Luftwaffe Antenna Feed?
Does the close-up picture show two conductors? If so, could it be Pyrotenax-type mineral insulated electric cable?

Re: Luftwaffe Antenna Feed?
I think the French means,private property do not pass this point.
More precisely Do Not Go Up In The First Place. No way that is an aerial feed.

Re: Luftwaffe Antenna Feed?
It looks to be a steel plate spreading the force of five through bolts, probably to hold something on the inside. Perhaps a hook for a heavy medal bestrewn uniform or a very large pair of 'powerful gestapo binoculars'

Re: Luftwaffe Antenna Feed?
I assumed that the insulated panel was a piece of decayed Tufnol or Paxolin sheet.
It could have been put there after the war to seal the hole. |
