2-30 MHz HF

Designed as a lightweight, quick to erect, NVIS antenna system, the 3028-900 HF antenna kit can be deployed as a stand alone or vehicle mounted system. Packed in a small carrying bag, the 3028-900 kit can be rapidly erected to provide an HF antenna solution for troublesome communication ranges. The system produces high angle radiation that is suited to short range ionospheric propagation (for example over mountain ranges).

Operating up to a maximum of 1kW, the antenna is suitable for use across the 2 MHz to 30MHz band when used in conjunction with an HF antenna tuner. NVIS propagation is normally dependent on local and seasonal ionospheric conditions below 12 MHz. The antenna system is supplied with a seven-section support pole to which four radial elements are attached. The impedance presented at the base of the system is similar to a conventional HF whip that can be impedance matched with an HF antenna tuner, either incorporated in the radio or as a stand-alone device. The system is supported using the combination of the upper radiating elements and adjustable insulated ropes attached to light duty ground anchors.

• Vehicle or stand alone applications
• Mainly horizontal, high-angle radiation
• The Shakespeare 3028-900 is similar to the AS-2259/GR NVIS antenna.
