Review on 📻 UAYESOK 5.9-Inch (150mm) NMO Magnetic Mount Antenna Base for Ham Mobile Radio - Magnet Mount with 5M (16.4ft) RG58 Coaxial Cable and PL-259 Plug - Ideal for HF/VHF/UHF NMO Antenna by Claudia Green

Bought these in addition after buying an antenna from this manufacturer and seeing a good quality product! Another order was delayed and not delivered within the promised time! There ended up being 2 but with different manufacturer names !The other is listed as "tram"! Both look the same and are probably made in the same Chinese factory? Seems well made but I haven't tried opening them to check how they are made! And after using a different mag mount it seems to work fine with its about 6 inch diameter magnet mounting a Tram 1180 dual band ham radio antenna on the roof of my car! (Addition: holds up safely at highway speeds!)
