HLPO430 Horizontal Log Periodic Omni Antenna 4-30MHz
The HLPO430 Log Periodic Antenna is a high-performance, omni-directional, horizontally polarized antenna designed for medium to long-range communication circuits.
The smooth omnidirectional azimuth radiation pattern provides reliable communications at all bearings. The two-layer stacked element design provides very high antenna gain characteristics and elevation patterns that provide the optimum take-off angle for each operating frequency.
Horizontal polarisation ensures that ground losses are almost eliminated, removing any need for ground screens or ground radials.
FEATURES / BENEFITS
Exceptionally smooth omni-directional azimuth patterns make this antenna ideal for long-distance ground-to-air and shore-to-ship applications.
The stacked element design results in optimum elevation patterns and take-off angles.
Horizontal polarisation removes the need for ground screens or radials.
Power rating options from 1kW to 25kW.
Available in standard and heavy-duty (cyclonic) wind-rated versions.
