The Travelling Wave Dipole Antenna is a highly efficient antenna for short to medium distance communications.

Codan’s TWD Antenna supports operation over the frequency range of 2 to 30 MHz, and is capable of full duty cycle voice and data operation at the rated power levels. Its radiation pattern is generally omni-directional, with a good combination of high and low angle radiation supporting both short and medium distance HF communications.

The large size of the antenna enables a very high level of radiation efficiency thus maximising on-air performance. The broadband design of the antenna eliminates the need for a separate antenna tuner unit, the antenna is connected to the transceiver via a single coaxial cable. Manufactured using materials designed for long service life, the TWD is built to survive in harsh outdoor environments.
