The broadband dipole antenna provides excellent performance for short to medium range circuits.
The antenna radiation pattern has a high take-off angle at the lower frequencies for short range communication circuits and a lower take-off angles at the higher frequencies for medium range communication circuits. At the lower operating frequencies, the azimuthal pattern is essentially omni-directional. At the higher frequencies, the azimuthal pattern approaches that of a dipole.
The broadband dipole antenna does not require tuning, thus eliminating the need for any form of antenna tuning unit with its associated losses. No terminating resistors are employed and so full power is available for radiation.
The broadband feature is ideal for multi-channel or frequency agile synthesized HF radio equipment.
The antenna comprises two horizontal conical sections, the elements of which are connected in the centre to a common feed line. The antenna is mounted between two guyed support masts.
