Bingfu 20-1300MHz Police Scanner Antenna Magnetic Base HF VHF UHF Two Way Ham Radio BNC Male Antenna Compatible with Uniden Bearcat Whistler Radio Shack Police Scanner

mounted on the roof of my building with a low noise amplifier and an SDR and i am hearing 50-75miles away with ease despite being in a mountain valleyyou need to set it up right but for what it is, amazing antenna for the money. perfectly adequate for everything it is rated for, including trunked/digital signalsthe antenna does pick up some noise so you can probably get better audio quality with other antennas, especially with strong signals, but for listening to voice etc it is perfectly sufficient, and the versatility price and range of capabilities makes it an easy buy in my bookof course radio quality and placement and general interference continue to matter, but my unit performs just fine even near power lines (see picture)

Antenna works good. The coaxial cable is rather small. It would be perfect for a car rooftop

Worked as advertised

As described arrived in good shape works great thank you

Device worked surprisingly well considering the bargain price.

I'm afraid I am disappointed. This antenna actually performs measurably worse than my Uniden 325P2 factory one. I have tried placement in a variety of spots. On top of my car (magnet does hold on well actually) on top of my house, which is taller than others because it's an older place that was built with high ceilings. It's probably 20ft off the ground up there and still couldn't pick up very strong signals. I have two towers in my county that are within ten miles of me and it struggles to receive either of them but my factory antenna receives them pretty well as long as I'm outside in the yard. I have only been using a P25 radio for a short while and something I've noticed pretty quick is these seem to be very vulnerable to signal obstructions. Even just being behind a wood wall can cut the strength in half if you aren't right near the tower you're receiving, and if you walk into a mostly metal or concrete building, forget it. You won't get a thing at all

Great product and price. Would purchase again.

This antenna claims 20MHz to 1300MHz, which is difficult to do for an antenna. Honestly I didn't expect much for $15, and my gut was correct. I have some very expensive equipment that shows on a good day, it might be OK above 400-500MHz, as judged by the VSWR graph. Sadly the VSWR graph is not much worse with the antenna whip unscrewed from the base. In other words, the coax is so lossy that any signal doesn't get through. and the antenna at the end barely does anything. I was hoping for better performance in the low band VHF, where my local CHP uses 38-40MHz frequently. You can see that at 38.5MHz, it has a 1:11 VSWR, which is utterly horrible. Note that in case you're not familiar with what you are looking at, lower in the graph is better.Real world performance even in the 700MHz to 800MHz bands are horrible. My scanner's stock rubber antenna used inside a car was about the same performance.The short version is that this thing is designed to look like an antenna, however seems to be a junk prop that does not perform as an antenna. Also keep in mind that these days if you buy it and want to return it, it will go to the landfill, so please save your time, money, and the environment.Do Not Buy!
