The HF Antennas used for long range communication (beyond 1000 KM) operate in frequency bands between 1.6MHz to 30MHz. The antennas can be made as broadband or single frequency (spot frequency) tuned type. The product range in this category includes :
- Omni Directional Antennas (vertically polarised) like Monocone, Slopy Dipole etc.,
- Directional Antennas like Log Periodic Dipole Array, Inverted 'V' etc.,
- Bidirectional Antennas like 'T' Antenna, Folded Dipole etc.,
- Steep angle Conifan antenna featuring Null Free radiation pattern for special defence applications such as communication in hilly terrains and forest areas, where the Ground wave communication is limited by obstructions.
