MX-6707 Thread size

[mm58]

Hello, sorry if this has already been gone over, but I'm looking
for the thread size/pitch of the threads on the top of the spring
on a MX-6707.


Thanks

Mike

Well I know a 3/4" NPT pipe cap makes a great weather cover for them.

Thanks for replying, but I'm pretty sure it's not pipe thread.

Best I can tell at this point, is that it's 1"-14, but I need someone to confirm that.

I was just saying that an NPT pipe cap has the same thread size and pitch for reference. I've used PVC caps on my antenna matching units for years to keep them clean and damage free. FYI, the AS3900 uses a 1" PCV cap

Referencing an NPT thread pitch gauge a 3/4" fitting has the SAE equivalent of 1-14 and a 1" NPT is 1 5/16-11

Thanks! I'm going to find a 1-14 nut and see if it fits

Did it fit?

Haven't had a chance yet

I measured my MX-6707 antenna threads, it is 1 inch diameter and 14 threads per inch. I also measured the AS-3900 it is 12 tpi, hope this helps.

as3900 is 1", 12 TPI? Good to know. I'll have to see about making an adapter for my faux CREW DUKE antenna.

Thanks for confirming the 1-14 threads!
