Review on Superbat Nmo Antenna Mount To PL-259(UHF Male) Cable (RG58 3M) Extension Cable With L-Bracket SO239 To BNC Adapter SO239 Coupler For Yaesu Kenwood HYT Vertex Icom Trunk Mobile Radios 1PS by Calvin Reynolds

For $20, disappointment. Where the cable connects to the NMO connector it's not very reliable or waterproof. For the price I would have expected a little better quality. I took hot glue, smeared it on the wire connection and sealed a small thin plastic cover that looks like it should protect the connection. I would not recommend this product. As received it is not suitable for exterior vehicle trim and will short out when wet.
