Technical description RHM-12

The Diamond RHM-12 already covers the shortwave spectrum from 7 MHz, the 6- and 2m band as well as the 70cm band ex works! Tuning is done quickly and easily by moving the radiator. This is labelled with markings, which make it possible to find the desired band in the twinkling of an eye. To extend or retract the radiator, simply operate a quick-release fastener.

When the antenna rod is fully extended, the RHM-12 reaches a length of 2.75 meters. 

Especially worth mentioning: For the lower bands (160m and 80m) we offer an optional coil set (Article 11467.12C).

Application description RHM-12

The RHM-12 is especially suitable for temporary portable operation. It is not waterproof and designed for higher wind speeds.


During operation, always make sure that the antenna is well grounded. If, for example, the antenna is operated with a magnetic base on a parked vehicle, this can be implemented using the Diamond MAT-50 magnetic mat (article no. 20060). When mounted on a tripod, several wire radials are suitable. For the 70cm band a separate, shorter antenna rod is available. No counterweight is required here, but a radial is included which can be used if required.
