UAYESOK VHF/UHF Mobile Base Antenna Ground Plane Mount Kit, PL259 to SO239 Adapter, 2m/70cm 136-174MHZ/400-470MHZ

Super quick delivery from the US to UK in about 3 days. Happy with that. Be aware that the threads that connect the radials to the base are inserts. One was loose so I nearly dropped and lost it. Nothing functionally wrong with it, just a loose thread insert that needed doing up. Fits well to the uhf/VHF antenna and coax cable, seems sturdy and well machined. I'm waiting for delivery of a vhf/uhf swr and power meter so I can't honestly review RF performance yet.

This assembly worked well. I was able to use it to measure the VHF and UHF SWR of various rubber ducky antennas used on portable ham radio devices. Needless to say, some such antennas bought on amazon were quite disappointing when compared to the original antennas that came with my Yeasu FT65, and the UV-K5 unit. Comes with 3 radials for VHF and 3 for UHF, but you can only choose 3. It would have been nice if 3 other holes would have been drilled and tapped so that all 6 radials could be used in one only VHF/UHF installation.

For what this is, it does good. For the other reviews thinking that adding this is going to improve SWR on the antenna. Get learned. SWR does not equal propagation.

Nice sturdy ground plane

Works great. Someone said it would raid my SWR but it clocked in at 1:1.06. I was going to build my own ground plane but after reviewing the cost of acquiring parts and materials, $15 for this ground plane was worth it, plus it looks better than a tin pie pan
