Need Information on a 'Johnson MATCHSTICK Multi-band Vertical Antenna'


 

I recently acquired what appears to possibly be a control box for a Johnson Matchstick Multi-band Vertical Antenna system.? A number of internet searches provided a few images on ebay and several auction houses but no meaningful information, instructions, manual, references to or about it.? Accordingly, I am reaching to the group for help and have attached three (3) images for reference.
?
If anyone has information, instructions, references, etc. and would share it with me I would appreciate it.
?
Tnx es 73.

Can't help much, I have no paperwork to provide. This takes me back well over 60 years, a ham who lived a few miles from me had one. Can't even remember his name or call now. As you surmise this is the control box for part of a complete EF Johnson vertical antenna system. I vaguely recall the antenna was well over 30 foot high, maybe closer to 40 foot and the tuning was done using the control box to select a motor located at the antenna base that matched the transmitter and antenna.?Don't even know for sure what was in the box at the antenna base, can only guess now. Sorry I can't provide any more information but at least I did see one once.

John,? it's ironic to me that you posted your question just days after I mentioned the Johnson Matchstick to a couple of buddies in an email.

When I moved to northwest Illinois in 1986,? there were still three electronics parts stores operating in Rockford Illinois, and like most they'd been around for years and at one time at least had sold ham gear.?? Having started to collect boatanchors I made the trip to each, hoping of course to find a Viking Desk Kilowatt in some dusty back room, but of course that didn't happen.?? However one store (whose name I can't recall) said the only piece of radio stuff they had was - you guessed it - the control box for a Johnson Matchstick antenna just like yours!? It was on a high shelf and the guy said it was probably only there because it wasn't worth the effort to climb up and move it.? I asked if they had the rest of the antenna, but he said the box was all they had, and I suspect that if it was in inventory, the outdoor components could have easily been mistaken for junk.? Or if it was installed on the shop as a demo antenna,? it probably wouldn't have lasted past the next roof repair.? In any case, the Matchstick evidently did not sell well for EFJ.

Sorry I can't be of any real help as that's the only time I've seen any part of the Matchstick and only recalled it last week while reminiscing about the radio supply stores we used to have.? It wouldn't be difficult to make your own relay-switched base loading coil that could be controlled by it, but there are probably better antenna options today.

Thanks for the reply, Bob.? I appreciate it.
?
One of the earlier replies from Mike, K5MGR, produced a QST ad from February, 1957.? Ya' just never know where these expeditions will lead.
?
My plans include careful disassembly, creating a schematic, cleaning everything, determining if it's a DC or AC circuit (runs on AC and switches with DC, I suspect), replacing whatever components need to be replaced and integrating it into some yet-to-be-determined multiband antenna system or other multi-device control box.? If nothing else, it's a really interesting find and might make an interesting tidbit in an Electric Radio issue somewhere down the road.

And I do have a Gotham V-160 Vertical still in the factory box that might marry-up to it.....
