Review on 📻 Bingfu Dual Band Mobile Radio Antenna VHF UHF 136-174MHz 400-470MHz NMO Mount for Car Truck Ham Radio Amateur Radio Marine VHF Radio Two Way Radio by Anthony Gupta

Mounted on an NMO mount on the metal roof of a 5x5 foot truck, this is the correct ground plane. The SWR was 2.5 or higher on the 2M and 440 UHF bands. The whip is too short. I replaced a similar but longer rod from another dual band 2m/440 ham band antenna. This is advertised as a ham radio antenna but it isn't or it should be pointed out that to be successful it is placed over a lousy ground plane. The black pin in the picture attached to the base caused an SWR below 1.7 on both bands with a good ground.
