Antenna Doublers (CI105, CI122, and GA35)

I was using sendcutsend to make a small part. They basically have a minmimum dollar amount to order, and the part is only about $5. Since I will need them eventually, I drew up a few quick antenna doublers.

I will be using the Comant CI-122 comm antenna, the Comant CI-105 transponder antenna, and the Garmin GA35 GPS antenna.

I 3D printed the doublers to verify fit, and sent them to sendcutset to have cut out of .060 T6 Aluminum. The .060 is probably overkill for the GPS and Transponder antennas.

I haven't received them yet, and I will include some pictures when I do.

I included the 3 STEP files in a ZIP.

They are really easy to make on your own and hopefully cheaper than these:

Yes, sendcutsend is making 2 of the comm antenna doublers, and one each of the gps and transponders antenna doublers for about $45. Between the materials, and my time, that’s a win for me.
