Hi All,

Yes, Radtech, I know they are very difficult to locate.
However, I think a few are still out there, just owners probably do not have a clue what they are for.
This is how the antenna looks when not mounted on the radio - not easy to tell what it is:

When these were surplussed in the late 40's they were surplussed without antennas. Apparently the government threw out the antennas.

So it's clear that I'm not going to find an LP-7 for my radio. But there is enough data on line now that I could make a pretty decent copy of one. So here it is. The hinges are hand made and are pretty close to what I can see that the originals look like.Image

good job on the hinges what did you make them out of?
did you use brass or steel square tubing?
I tried to use hinges from Rockler, but they were not strong enough.
I used brass tubing.
Thanks

I used steel. The hinges are pieces of 18 and 16 gauge. The pins are 10 gauge wire peened into place. I know that the originals were made of brass but once painted OD who's going to notice.
