HF Directional Antenna
LPMA-A0010
The LPMA-A0010 is an HF monitoring, high-power and communications antenna covering the frequency range 2 to 30 MHz, with powers of up to 2.5 kW continuous. This LPMA design offers superb performance over the entire HF frequency range. brBecause the LPMA-A0010 is vertically polarised, it offers effective ground-wave coverage, and is ideal for signal interception or communicating with HF vehicle and manportable radios, which typically use vertically polarised antennas. It also offers an excellent low-angle radiation pattern, making it equally suited to medium- and long-range communications links.brThe LPMA-A0010 is intended for installation on fixed towers at a permanent site. The antenna is rated for wind speeds of up to 160 km/h, depending on the specification of the towers used.
