Changing The Coax Connector on MFJ-4601, Window ANT Feedthru


 

开云体育

I have an older MFJ-4601, I would like to change one of the SO-239 to a “N” type connector.

I was wondering how hard is this going to be? Are the panels glued to the board?

I don’t want to destroy this in the process.

I have a 1.2ghz antenna, it uses “N” connector.

?

Thanks in advance.

I changed some. No problem loosen the nut and out it comes you don't need to mess with the panel. The problem is that a standard N barrel isn't long enough to seat a male on both sides you need a longer barrel.
I used a "MPD Digital 3-Inch Extra Long N Type Female Threaded Bulkhead Barrel Adapter" from Amazon?? ? ??

Thank you for all that replied with ?answers.

I just received the MPD female connecter I ordered.

Hopefully it will warmup a little in the next week or so, It shouldn’t take more than 10 minutes to replace.

Then I can replace the insulation in between the windows. ?

I ordered the 4602 entry panel from them, but I ordered it with N connectors instead of PL style, and there was no extra charge. PL-259 fittings are junk in my opinion, and are best used for audio applications, cause that's about the limit of their frequency response!
