@PACNWComms @Sshannon Yes, the KG-1000G Plus has a SO-239. Once everyone pointed me in the right direction on who makes a good product I contacted PolyPhaser and they recommended the IS-50UX-C0 for my application. It has the SO-239 connectors. I asked about the N connector because I have read and watched a lot of discussion on this subject. He stated that since I will be using the M&P EVO connector that there really won't be a significant difference. I did do some reading on PolyPhaser and and they appear to be "top shelf" stuff.
Other than the radio and power supply, I have been in a planning mode, trying to figure out what will work with what. So now that I have more information, I just need to roll it around in the bean for a bit before pulling the trigger. Then I will be ordering the cable, surge protector and antenna all at once.
Thank you again for pointing me in the right direction.
