Review on 📻 Bingfu 20-1300MHz Police Scanner Antenna - Magnetic Base, Radio Scanner Antenna with BNC Male Connector - 2-Pack, Compatible with Uniden Bearcat, Whistler, and Radio Shack Police Radio Scanners by Walter Martin

The perfect antenna if you are looking for something small and compact. The antenna has good reception because it is designed for reception over a wide frequency range. It's not a big antenna. See the photo I've attached. Size depends on use, but if you want a cheap external antenna this is excellent value for money. I can ask someone with a calibrated meter to test it and if so I will update this review. You can't beat the price if you don't care what frequency it's actually tuned (designed) to.
