Question

Hello everyone.

I’m new to the forum so please be patient with me.

I’ve read through as many posts as possible, and came kind of close to an answer, but not fully.

I have a Jeep Wrangler that has a fiberglass top.  So my question is; how and where do I mount my GMRS antenna to benefit a ground plane?

If I mount it to the metal tailgate, does it use the rest of the frame and metal parts of the body as a ground plane? I personally don’t think so, but instead of redesigning the wheel; I’m pretty sure that some of you have already conquered this quest.

Thank you in advance for any constructive replies.

You can buy an adhesive metal disc and stick it on the aluminum hood.  I placed it near the back of the hood, but several inches away from the back edge to provide a bit of ground plane to the back.  And several inches away from the side edge as well.  I also ran a grounded wire in the slot at the edge of the plastic cowl, forming a ground radial in the backwards direction.  All of this keeps it away from tree branches fairly well, and if it's a short antenna then it isn't too much in the way of the field of vision.

Mine is a Midland MTX275, which came with a little 1/4 wave antenna with 20 feet of thin RG-174 coax.  That coax eats a lot of signal.  If you have this, either get a better antenna or chop the coax down to size and install a connector.  Even better, what I did, chop the coax to one foot to get under the hood, then use connectors and an adapter to run RG-58 the rest of the way to the radio.

For the JL/JT, there is another post here somewhere showing how to route the cable under the cowl and through the driver's door leading edge. It works great.
