AT LPA - HF Log Periodic Antennas

AT LPA HF Log Periodic Antennas

Our HF Broadband Log Periodics are almost 100% efficient and are short to medium range antennas. They can be supplied in a number of models to suit differing frequency spans. They are high gain and directional and can be configured as bidirectional if two are mounted back to back.
The antennas are end 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. Radiation is horizontally polarised

Full lightning protection is provided
