Thanks again all.
@popnokick i do not have access to anything outside the window i can anything on. I did however by this antenna, figuring i could drape it out of the window:

Sweet Jebus! $70 bucks for the antenna is W-A-Y out of line. That's about $10 in parts, if that.
There are a lot of good tutorials on how to make a "roll up J-pole" online. It's not hard to do, and it'll save you $60 that you can spend better elsewhere. Also, look at 1/4 wave ground plane, or any other easy to home brew ham radio antenna you find on the net. It's not hard to do and it teaches you a lot more than just buying stuff on Amazon.
Problem, though, is having antennas like that inside an apartment, or even right outside the window.
-Antennas work best when they are up high and in the clear. May not be possible with your installation, but don't spend $70 on an antenna to find out.
-Antennas that close to you and all the others in the building means it's going to suck up every bit of RF interference it can. Again, find a way to get it away from the apartements.
-Transmitting antennas that close to TV's, phone wiring, cable TV, FIRE ALARM WIRING, whatever else is in the walls is going to be a problem waiting to happen. You need to get it away from the building if you can. Keying up your radio and setting off the fire alarm/smoke alarms, screwing up the TV's in the building, etc. is going to give you a lot of headaches you don't want.
But, with some careful pondering, you can make it work. Keep power output low. See if a temporary installation is possible. Some take a 5 gallon bucket from Home Depot, stick a piece of pipe in it, and fill it up with rocks or concrete. Instant antenna mast. Mount a decent antenna on it, run the coax through your window, Boom, Bob's your uncle and you're on the air. When you are done tickling the airwaves, take the whole thing inside and stick it in the closet.
So go NMO for the car- that is solved. As for the connection, is it better to just use the SO-239 or will putting an adapter on the end to accept the N connector be a better solution?
Popnokick brings up some good points. Find an antenna that works for you and go with it. No one really cares what brand you use. If you are asking advice, you'll get a ton. I'm one of those he speaks of that will direct you to the professional grade antennas. Yep, I have 30 year old Larsen antennas that are still working like new. All the cheap Chinese ham antennas I bought years ago long since failed/broke/fell apart. Your choice, though.
Trying to learn antenna theory, but i'm sure that will take a few weeks. I would like to be up and running on the anytone this week.
Rushing your antenna installation will lead to disappointment. It's the most important part of your system. Yeah, get on the air as soon as you want, but you may be disappointed if you rush this and end up with a cheap antenna in a less than ideal installation. That'll sometimes really take the wind out of your sails.
