So ive been a ham for about 8 months now and I mostly just do HT stuff but I finally picked up a used Yaesu FTM-400 and want to get it properly installed in my F-150. I've watched probably a dozen youtube videos on this and I feel like I have a general idea but there's a few things I cant quite figure out and wanted to ask people who have actually done it.

First thing is the antenna. Truck has a bed so I was thinking mag mount on the roof of the cab for now just to keep it simple, but everyone seems to say NMO is the way to go long term. Is it worth just doing the NMO mount right from the start or is mag mount fine for everyday use? The other thing is power — I keep seeing people say run it direct to the battery and not use the fuse box, but the fuse box seems way easier. Is there actually a reason to avoid it or is that just the hardliners talking. And do I need to do anything special since its a newer truck with all the electronics in it, like noise issues or whatever. Sorry for the rambling post just want to make sure I dont screw anything up before I start.

Good questions and smart to ask before you drill anything. On the antenna — honestly just do the NMO now. Mag mounts are fine temporarily but they move around, the cable gets pinched in door frames, and you'll end up doing the proper mount eventually anyway. Might as well skip the in between step. A lip mount or a through-hole NMO on the cab roof will be way more stable and you'll get better ground plane contact too.

On the power question, running direct to the battery with an inline fuse is the right call. Fuse panels in modern trucks often share circuits with stuff that can cause interference, and the wire gauges on those circuits aren't always rated for the current draw a 50 watt radio can pull, especially on transmit. Just run 12 or 10 gauge wire with a fuse close to the battery and you'll be good. It sounds like more work but honestly it isnt that bad and you'll be glad you did it.

Newer trucks can definitely have noise issues but a lot of people install without any problems at all. If you do get ignition whine or alternator noise there are a few things to try — engine ground strap, ferrite chokes on the power leads, etc. But dont pre-solve a problem you might not have. Get it installed first and see how it goes.

yeah what he said on the NMO. i put a mag mount on my jeep when i first started and regretted it almost immediately, scratched up the paint a little too which was annoying. did the drill and mount a few months later and its been solid ever since. the FTM-400 is a great radio btw, you'll love it once its in there
