Does anyone make a plug to go into the factory antenna hole , when you are using a DSM system? Thanks for any info.

I'm not sure. I would like to have one also. I have seen some guys with a plug,not sure if they made it themselves or purchased one. I still have my antenna in my radio

I would also like one. Too bad it couldn't be removed completely and cleanly. Apparently, Futaba wasn't thinking that far in the future.

If you have ever bought a sintered rotor for a brushless motor, the rubber end caps of the container that it comes in is a perfect fit.

They are on back order, but I put in my order today. Thanks for the info.

This is another source for the antenna plug

Go to your local hardware store. They make plugs that are plastic that fit exactly into antenna hole. I'll try to get a pic up here when I can figure out how to.
