NEW to GMRS. Got my license, purchased a Midland MXT400 AND the 6db antenna. 

I'm mounting this opposite my CB antenna on the hood-one is passenger side, the other drivers. 

Do I need to tune this setup like I did my CB once its installed? The antenna came with a small allen wrench and a set screw where the whip enters the spring base. 


I have a SS bracket made for the Jeep hood contour but it's drilled out at 1/2" for a CB style antenna mount. The GMRS antenna comes with a plastic insulator bushing that requires a 5/8" hole. I assume I can enlarge the bracket and that should be good. 


My goal for this setup is off road comms and maybe some casual station monitoring and playing around with repeaters. I'll have to do more homework on that once I get things installed and operational. I am pretty familiar with the CB world but GMRS is something new. 


Not looking to go full HAM but that is always a possiblility down the road. For now, just want to get the GMRS up and running.

You are good to go with the antenna. Its pre-tuned.

Just be sure the negative side is properly grounded, add a ground strap from the hood to the top of the inner fender and the common ground under the hood or the negative side of the battery. You will see improvements with CB performance, too.

Hi, Keith here. Im in Washougal Wa. Just East across the river from Portland Or . The good side of the river.

You will do best if you can mount your antenna in the center of a 61/2 in of metal that is well grounded

Be vewy vewy quiet.
I'm listening to my wadio!
