Hello all. I recently bought a Radioddity UB-15G for use in my 2023 Ford F-150 work truck. The radio came with a small magnetic antenna, about 6-9” in length. As the truck is made with aluminum instead of steel for the body panels, I have a 90mm circular steel disc secured to the roof using VHB tape. The magnetic antenna is in turn held in place on the steel disc.

I am new to the world of radios, but from what I understand, the small steel disc on the aluminum roof is a less than ideal ground plane to provide good reception. My goal is to improve my reception without making any permanent modifications to the truck.

Would a magnetic no ground plane antenna on the steel disc on the truck’s roof work? Should I look at a different mounting solution?

Ideally, I’d be able to temporarily remove the antenna for low overhead clearances and drive through car washes. I understand this may not be be realistic and I am keeping that in mind.

Any help and input is appreciated. Thanks!
