Couterpoise Magnet Mat
Magnet mat as couterpoise for HF mobile antennas
Every shortwave mobile antenn requires a good and reliable counterpoise. But with some installations that's hard to achieve, for example when using a clamp on the roof railing or when using a small magnet base.
This problem can be solved with the new magnet mat from Diamond. Just put the mat on a flat surface on the car and connect the included wire to the antenna base.. Due to the large capacity between mat and chassis metal the HF resistance is greatly reduced. When operating on 3.5MHz two of these mats are recommended. When operating on 50MHz the connecting cable should be as short as necessary (less than 20cm).
- Frequency range: 7 to 50MHz (3.5MHz with two mats)
- Max. Power: 500W (SSB), 200W (FM,CW)
- Adhesive force: ok up to 110km/h (without wind)
- Size of mat: 80 x 195mm
- Length connecting cable: 30cm
- Weight: 55g
- Accessories: 16mm ring, heat shrink tube

Especially long antennas can't be mounted safely on the top of the car because that would violate the max. allowed height. And the sheet metal might not be solid enough...

Of course this mount is also suitable for cars with aluminum chassis, where magnet mounts cannot be used. Please observe the local vehicle and traffic regulations! Use while driving is not permitted AFAWK.
