Stealth 9310 automatic antenna 1.8 - 30 MHz Stealth 9310 is a motor-tuned antenna with a total length of 2.5 m and 200W power handling. The lower part is 84cm long and contains drive electronics. The upper part is a 1.5 m glass-fibre rod with a spring.

The antenna is for the full range from 160-10m. Unlike other antennas which operate mostly on the 'screwdriver' principle with DC motor and spindle is here a stepping motor and a toothed belt responsible for tuning. Thus, the antenna needs to tune a maximum of 0.5 seconds!

For automatic tuning, there are suitable adapter cable for the TUNER jacks of the usual HF radio equipment available. But the antenna can also be operated without the interface ... just only transmitt. The tuning characteristics of the internal controller can be adjusted via the USB port of the antenna with the supplied software, individual of the vehicle.

The antenna is manufactured in accordance with MIL-STD 810G and totally waterproof (IP68). Of course, the antenna is suitable not only for vehicles, but can also be used stationary or portable. For mounting on a foot, the 9310 has a 16mm threaded bolt. Various mounting brackets for vehicles or masts are available.

The NVIS kit is designed to replace the standard whip. The whip can be carried as a backup in the car.


The kit is made of high quality materials. Cladded fiber radiator, copper mesh, stainless steel machined and anodized aluminum stand for a long shelf life. The NVIS kit contains all parts for installation on vehicles with such a triple magnetic base.


The NVIS kit improves the performance of the antenna by 5-8dB. The tuning range is limited to 1.6 - 16 MHz. Also the angle radiation is increased by this KIT. If previously there was a dead zone between the ground wave and sky wave, the NVIS kit improves communication over short to medium distances (20-500km, see diagrams).

STEALTH Universal Gibbet Mount

 Massive universal bracket for mounting the antenna to balcony railings, masts, or on larger vehicles.

The boom consists of a horizontal square tube 50x50x3mm with 850mm length and with a 300mm high antenna carrier. The other end of the arm is open, here you have to place your own mounting holes. Alternatively, the boom can also be welded. If necessary, the boom can of course be cut to the required length. Two holes for water drainage are available. The vertical part can be mounted in different positions (left/right/45 °) on the boom. On the upper mounting plate, the STEALTH antenna is mounted.

All parts hot dip galvanized steel, Weight 5,8 Kg.

Tarheel Radial kit

 The massive stainless steel plate (6mm) is intended for use on the same pole where the antenna is installed. Max pole diameter is 35mm. The plate has a diameter of 23cm and offers 20 screw--contacts for radial wires. Included in shipment are 10 readials of 275cm length each.

There is no need to lay out the radials strictly in a star pattern. You can bend the radials, leave out some areas, just as the surroundings allow. The only limitation is that the radials should not cross over each other.

The radial plate should be installed as close to the ground as possible, the antenna as close as possible above it. All parts are made of stainless steel, except the wires.

11930.GR Radial kit 86.30

Radial kit 30/40/80m for vertical antennas. Consist of two λ/4 wires per band. Uses PVC coated braided copper wire 1.5mm2. Includes solder lugs on one end for easy connection to ground post.

These radial kits can be used for elevated antennas (not ground mounted). The radials should be installed so that they do not touch the ground, nor the roof nor any other obstacle. If the vertical antenna should be installed on the ground other radials are required (at least as long as the antenna is high, better longer, as many as possible, not less than 10).

Excellent explanations about antenna radial systems are provided by some manufacturers, for example by SteppIR and Bencher (english text):

Couterpoise Magnet Mat 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).
