The Semi-delta Antenna is an economical broadband base station antenna suitable for short to medium distance HF communications.
The compact design of the antenna makes it suitable for installations that have limited space available.
The Semi-delta Antenna supports operation over the frequency range of 2 to 14 MHz, and is capable of full duty cycle voice and data operation at the rated power levels.

Capable of full duty cycle voice and data operation at the rated power levels
The antenna is an omni-directional antenna but has a good combination of high and low angle radiation to support both NVIS and longer distance HF communications
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 Semi-delta is built to survive in harsh outdoor environments
