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 Robert Farrar

Bought this extra after buying this manufacturer's antenna and seeing a good quality product! Another order was delayed and not delivered within the promised time! As a result, there were 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 to be well made but I haven't tried opening them to see how they do were manufactured ! 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!)
