AT HF Biconical Dipole Antenna

AT HFB 2-30 Biconical Dipole Antenna

Our HF broadband Biconical Dipoles are highly efficient, horizontally polarised antennas that at lower frequencies are suitable for short to medium range communication and at the higher frequencies have the strongest signals at lower angles for long range propagation.
The antenna is centre fed and can be supplied with power ratings ranging from 200 watts, to 10 Kilowatts CW (Continuous). The antennas are almost 100% efficient across the full operating range of frequencies. The antenna is ideal for frequency agile transmissions and is constructed of high grade materials throughout.

Full lightning protection is provided
