Genuine Nagoya Antennas
Nagoya antennas are each individually analyzed to ensure compatibility with your radio.
Nagoya Antennas are dependable, accurate, reliable, and affordable.
Avoid antennas that pretend to be a Nagoya. Antennas that are not individually tested or tuned can cause high SWR, which damages a radio.
Nagoya Antennas are proven to be a reliable and safe antenna manufacturer.
The GPK-01 not only facilitates easier antenna deployment but also significantly boosts your radio's transmitting gain in comparison to standard factory antennas. Depending on your specific needs, choose the ideal antenna length for the perfect balance between portability and performance. With the GPK-01's 200W power rating and 100 MPH wind load capacity, rest assured your antenna setup is built to last, regardless of the environmental challenges.
- 20.5" Ground Plane Radials
- Easy Installation on any 2" Pole or Pipe
- 200W Power Rating

Versatile NMO Mounting Options for the Nagoya NMO Series Antennas
RB-50: Magnetic Vehicle Mount
The RB-50 is a magnetic mount that is ideal for vehicle users looking for a quick and effortless installation. It boasts a strong magnetic base for secure attachment and comes with 18 feet of RG-58A/U cable, complete with a PL-259 connector for a reliable connection to your radio setup.
RB-100N: Versatile Drill or Bracket Mount
For those who prefer a more permanent mounting solution, the RB-100N is an excellent choice. This mount can be installed either by drilling a hole to support the NMO mount directly or using the included L bracket for attachment to a vehicle or to a grounded location at home. It includes 20 feet of RG-58A/U cable, allowing for greater flexibility in antenna placement.
RB-700N: Convenient Lip Mount
The RB-700N is a versatile and user-friendly lip mount, perfect for those needing a secure yet non-invasive mounting solution for vehicles. It easily attaches to doors, trunks, or any metal lip, and features rotatable adjustments for flexible antenna positioning at any angle. This ensures optimal signal reception. Protective pads are included to prevent vehicle surface damage. Additionally, it comes with 20 feet of RG-58A/U cable for convenient antenna placement, enhancing your radio communication's quality and reliability.
GPK-01: Ground Plane Kit for Base Stations
The GPK-01 ground plane kit is designed for temporary base camps or home antenna setups. This kit enhances the performance of NMO antennas by providing a ground plane, and it features grounded radials. It's designed for easy attachment to a mast or in-ground stake, making it a versatile option for stationary setups. Cable is not included, and you would need to supply your own run of PL-259 Coax

This is very useful, works with different antennas too.

This is a Bulkhead PL-259 connector NOT a NMO mount and it's performance shows. Absolute junk, antenna on a magnet mount on a cookie sheet at 5ft high works but place the same antenna on this mount 25ft up in the air and NOTHING.

This is an excellent replacement for the white antenna typically used on a house. My HOA said no the fiberglass stick but a mobile antenna has not been seen and works great.

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.

Mounted this to a pipe on the roof of a building, installed an NMO mobile antenna, done. Checked SWR, all good. Plenty of ground plane for VHF or UHF.Only complaint it the metal is a little thin and slightly weak, especially at the 90 degree bend from vertical to horizontal. With a taller antenna and some wind, it'll bend and not stay vertical.

Item as advertised.Easy to install with a mobile antenna giving it a good ground plane. Mounting bracket not too bad either.Does come with UHF radials and additional extensions to make it work better on VHF.Well constructed and looks fairly sturdy.

Nice ground plane set needs an NMO plug though or some kind of convertor

This review is about the ground plane kit:It's a ground plane kit -- it works. However, I found that only one of four set screws on the radials would work. The threads were cut too deep, so the screws would not engage with the thread while the radial was in place. Since I was preparing a semi-permanent installation, I just ended up soldering the radial parts together.

I mounted my vhf NMO mobile antenna on it at a height of 22 feet. I receive stations up to a 50 mile radius. Works great.
