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

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.

Works well will all my vertical antennas on both bands. Comes with 3 Solidly Built Radials for each band but I find using two of the short radials for 70Cm and one for 2M take care of both bands without having to switch out. This kit does improve SWR for most of my antennas whether it be on my HTs (with adapters) or way up in tree. Actually bought this the PL/SO 239 collar to use as an HF Antenna Ground Radial Connector for an ATAS-120a and Comet Toybox HF Antennas... But will buy a few more just to have. Great solid product. NOTE: Be careful if using in trees and go slow when moving past/around branches. If you take care, then you'll have no problems.

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

Noticed difference's on receive and transmit I highly recommended. SWR drops too HAWAII APPROVED 🤙🏽🤙🏽🤙🏽

I’ve not seen any difference in my transmissions. I’ve mounted them all different ways. The results were always the same. Maybe it was the fact I mounted them on magnetic mount.

The radials are too short for 2m ham band. I kept it because has 3mm threads for the radials and I made my own. Basically I bought an adapter I ended up with about 30" radials to get the SWR down to 1.2:1.

I use this ground plane kit on my Baofeng UV5R radio and was able to reach a repeater 32 miles away. However the installation was not ideal I have to use a so239 to SMA female adapter between this kit and to the radio antenna port, then I have to use another adapter, so239 to SMA male to connect the SMA female antenna. I tried both the VHF and UHF with the longer radials and GMRS with the shorter radials. In all three tests the ranges of TX and RX were greatly extended. If you don't mind using two adapters and have less than sturdy handheld setup this kit is better than any antenna by itself.

This does absolutely nothing to help transmit or receive. It’s worthless and a waste of money

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.
