Review: PORTABLE - EASY TO USE - INEXPENSIVE - Quite functional, works well to adjust a mobile antenna's ground plain and general experimentation. The magnetic pad sticks well to my car for good contact. It's easy to install and remove so it's portable. I've used mine for weeks now and I must say that I have seen changes in signal strength based on frequency and antenna. Do your research first.
Review: Simple solution that works great - I bought a Yaesu ATAS-120A antenna but had problems getting it to work on the 20 meter band when mounted on a mag mount on my van roof. SWR was too high. I bought the GRA-MAT50 MK2 counterpoise magnet mat ground plane and tried it again. My FT-710 tuned on all bands between 40 to 6 meters with a good SWR while testing, I made an SSB phone contact with a POTA activator in Spain on the 10 meter band. Excellent! I'm pleased with this magnet mat ground plane.

## Features

- Easy to use: Simply place the mat on a flat metal surface and connect the supplied wire to the base of the antenna for a quick and effortless setup.
- Improved signal: The large capacity between mat and the car chassis reduces the HF resistance, resulting in a stronger and more reliable signal.
- Frequency range: The frequency range of the GRA-MAT50 is from 7 to 50 MHz, making it suitable for various HF mobile antenna applications.
- Increased coverage: For operations on 3.5 MHz, the use of two mats is recommended for increased coverage and signal strength.
- High power handling: The GRA-MAT50 is capable of handling a maximum power of 500W (SSB) and 200W (FM, CW), making it suitable for various power levels.
- Weather-resistant: The latest version, the GRA-MAT MK2, is made with a soft magnetic material and copper coating for durability and style, and is suitable for use in all weather conditions.
- Adhesive strength: The mat has an adhesive force that can hold up to speeds of 110 km/h without wind, making it a practical solution for those on the go.
- Portable design: With its small size of 80 x 195mm and lightweight of 55 g, the GRA-MAT50 is easy to handle and transport.
- Cable length: The included connecting cable has a length of 30 cm, providing sufficient length for most installations.
- Versatile use: The GRA-MAT50 provides a solution for using an RF antenna on a magnetic mount, making it suitable for various installations, including those on balconies and with magnetic bases.

### ⭐⭐⭐ On the fence
*by R***Y on December 23, 2024*

I picked up the GRA-MAT50 MK2 Counterpoise Magnet Mat to pair with my magnetic mount and HF antenna, and I’m left with mixed feelings. On the positive side, it’s a clever concept with an interesting form factor that magnetically attaches to the car, making it super easy to use. However, I’m not convinced it actually improves performance, at least on HF frequencies—it just doesn’t seem to make a noticeable difference. Perhaps it might have more impact on VHF or UHF, but for HF use, I’m not seeing much value. While it’s a cute and innovative idea, I can’t justify giving it more than a 3 out of 5.
