Review: The antenna had different thread spacing and would not attach to my NMO antenna mount. Disappointing.
Review: Very nice unit. Loss is at normal level for vhf/uhf. Would be nice if they use lower loss cable. Yes, make the coax thicker but I could live that.

*by Y***Y on 12 May 2024*

Got this ground plane kit to test on my mobile rig. Tested this two different Comet antenna. One is a Comet CSB790A and a Comet CA-2x4SR. Both are dual banders. Though these antenna are mounted on a 1"x2" extrusion style rack. Though I have a decent grounding from the rack to the steel roof on my 1999 Toyota 4-Runner. This ground plane kit helps with the SWR a tad bit. On the Comet CSB790A antenna. It's a UHF style and I got a NMO adapter for the antenna mount. So with that being said. I tested the SWR and wattage output from my ICom 2730A mobile radio with the MARS mod using a Surecom SW102 meter and a Sysjoint NanoVNA-F V3 analyzer. One to test the harmonics and resonance of both antenna on 2m and 70cm bands. Both were tested on the 2m and 70cm calling frequency. Was able to make several contacts about 40+ miles away with full quieting. This kit did improve a tab but nut I don't plan on using this while being mobile. This kit best work on attaching the supplied stainless steel bracket to a post or pole using two supplied heavy duty hose clamp where there's no flat metal object to use a ground plane. I haphazardly attached this to my wooden fence and it did to reduce and lower the SWR quite a bit. Everything helps when you're trying to make that connection either simplex or trying to hit that long distance repeater long distant away. Also Nagoya said you can use this while mobile but my highly not the SWR don't help much or at all. But word of caution is that if you wish to use this while driving. I would recommend use medium strength thread locker on the hardware before you start driving. Great ground plane kit with no issues other than the set screw is small. I almost 4 of them. I would recommend this to any mobile HAM operatiors especially when you're at park with just a wooden post or tree you can attach the bracket to.
