Review on 🚗 Bingfu Universal Car Stereo AM FM Dipole Antenna with Hidden Adhesive Mount for Vehicle Car Truck SUV Radio Stereo Head Unit Receiver Tuner - 10ft Cable with DIN Plug Connector by Anthony Epps

I bought this unit for AM reception only, to test old AM car radios in my office. After lots of experimentation, I've found that using a 2ft alligator wire for AM reception works a lot better than this antenna, unless I'm standing and holding one end of the antenna (the other end in particular doesn't help). I tried to fix it everywhere - in the windows under the ceiling, dropped it on the floor. I've tried wrapping it in tinfoil (helps a bit), tinfoil strips, tinfoil fans, whatever. For the life of me I can't figure out why this antenna isn't working very well. It appears to be well constructed and the end of the bracket fits nicely into the car radio jack.
