Hello,



I am looking for some (apparently) special coax connectors for my 

Apollo (now Garmin) nav/coms. The old connectors are made by Delta 

Electronics Manufacturing Corp., part number 4205018N995-000, and 

are slip-on on one side with a metal flare to help guide the radio 

coax connector into place, then a center-wire solder and twist-on 

shielding connection the other end. There are two rectangular 

flanges for mounting to the nav/com tray.



I am told that these are standard for the older Apollo radios but 

they are somewhat difficult to come by. If anyone is selling any or 

knows of anyone who has any, i would appreciate it.



These connectors float on the tray, which also helps for easy 

alignment when sliding the radio into the tray. I just need new 

connectors so I can switch to my RG400 coax from the RG58. Let's see 

if I can add some photos.


	


   Those are a real odd-ball tray connector for coax.

   Most manufacturers went with the TED 9-29-10

   connector . . . legend has it that they designed

   that connector for Ed King waaaayyyy back when.

   They became popular and were adopted by almost

   everybody and are still in production.

   I've never encountered the connector you've cited.

   If you could get me some clearer photos, I'd like

   to add them to the archives.



   As to your particular question, are you replacing

   RG58 because it's damaged or now too short? As

   Kelly pointed out, unless there are mechanical

   reasons for replacing the coax, performance gains

   for replacing it are trivial.



   Can you unscrew the cap on the back of the connector?

   I think you'll find an access port to a soldered

   connection to center conductor under that cap.

   I note that the shield connection appears to be

   the legacy BNC-style clamp-ring and gasket. With

   some care on the workbench, you can salvage and

   reinstall the old connector.



   If coax replacement IS indicated, you can also

   cut off the old RG58 to leave a 6" or so

   flying lead which you can terminate with a cable

   female BNC . . . then extend your new installation

   from that point without risk to the old connector.



   I'll bet that critter is not easy to find and

   probably expensive if you do find it.

Hi Bob,



I don't believe he's talking about those (king/icom/etc..)...I think

specifically the Delta P/N mentioned used by Apollo/UPSat/Garmin...which are

these (not my picture):

As noted, you can easily install RG58 or RG400 into this connector and they

are reusable.  They are rare because they are no longer in production, but

we have a slew of them in stock just due to normal business with these over

the years.  What's harder to find is the little shoulder nuts that allow

those to float...we have to turn some down by hand on the lathe if we need

them!



Cheers,



Stein

Oh!!  



Stein, can you send me that schematic in the background (installation instructions for this Delta connector) of the image you attached to your reply? Knowing the proper installation procedures would help if I have to re-use the old connectors. 



From your image I see that RG400 can, in fact, work in this style of connector. That's very reassuring. 



Rather than leave a pig tail of RG58 on the back of the tray, I'd rather go with RG400 the whole way. 



I've been busy and have not been able to locate any Delta Electronics Manufacturing Corp. distributors: DEMC would not sell directly to me as I'm not a business. Stein, if you know where I could get 4 to 6 of these connectors that would be great. Just the installation instructions though would be a big plus.
