I'm going to machine one of these this weekend for a friend and thought I would put this out there to see if anyone else was interested.
Update 1/31/21: The price will be $45 shipped for one antenna.
Prototype Photos:


The length of the part is based the depth of the large antenna cylinder which is just under 1/2". If the depth of your cylinder is less (i.e. 1/4") just let me know and I can adjust the length, which won't be much.
To install, just use a 5/16" drill bit to drill a hole at the center of your cylinder.
If you're interested, please post a reply with the number of parts needed. Thanks.

1. CE (Done)
