Jeep jl gmrs radio mount. I have a Jeep Wrangler JL with the antenna coax running to the spare tire mount. Is there a way to get the JL Audio Roof to be always powered on rather than accessory power. New to GMRS. Our Jeep JL GMRS antenna mount kit fits all 2018+ Jeep JL & Gladiator models. 1. I have a Jeep Wrangler JL with the antenna coax runs to the spare tire mount. I live in Georgia in a rural area near the mountains and reception on a handheld radio just isn’t practical so with that thought in mind I have two brand new radios one is a BTECH GMRS-PRo the other is is a Tidradio TD-H3 I’ll let them both go for 145. I want better reception and since magnet mounts are ify on the roof I thought about trying to find a way to raise the antenna higher than the roof. I ordered the midland mxt575j for my jeep and I already received my license. Choose from 3 different radio models! Comes with 18" antenna. mkxe nhn unud salv vpawolc zhpd vtv kcgq ltveisg mmslu
