Review on Bingfu Police Radio Scanner Antenna - High-Quality Telescopic BNC Male Antenna for Uniden, Whistler, and More by Jay Sterns

I don't know what "metal" this antenna is made of, but a few seconds after I took it out of the box and installed it on the back of my scanner, the outer laminated material started to peel off to detach . This revealed what was underneath the light gray plastic material. I have had many of these telescoping antennas over the years, I have never seen any of these designs before. The antenna will not stand upright when fully extended, it will fall under its own weight. Also, the reception isn't very good, it pulls fewer channels, less clearly than the standard Uniden antenna, which is 18 inches shorter. I would not recommend that. Product due to the cheap materials from which it is made.
