Fan Dipole Antenna

The Hilomast, LLS multi-frequency antennas are designed to give a low-cost compact antenna for short to medium range omni-directional or bi-directional coverage on up to four spot frequencies in the HF band.

The SMC/MCFD/N antenna is designed for installations where two masts can be used, while the SMC/CFD/N antenna is a more economical version using only one mast. Both antennas use the CCJ/1 coaxial cable junction unit which has a built-in suspension point for the coaxial downlead, therefore, ensuring that the weight of the cable is not taken by the termination. The antennas are designed for fixed or temporary location and are constructed of high-quality components. The elements are of multi-strand hard drawn copper magnesium fitted with line taps and end insulators.

Several versions are available with the number of elements normally equal to the number of spot frequencies required. Some coupling between elements will occur, which affects the VSWR, so final adjustment can be made on-site quite simply by adjusting the line taps on the ends of each element. For this reason, the elements are supplied cut over-length.

All installations are delivered complete with halyard straps, D shackles, insulators, and the CCJ1 junction unit which can have UHF type N or any other termination to order. Coaxial cable to customers’ requirements complete with connectors. Masts for light or heavy duty, lighting kits to International Civil Aviation Organization (ICAO) standards and mast erection equipment are all available.

For economical installations, we would recommend the PA2 alloy mast or the telescopic mast. Where antennas are to be used in extreme environments, we would recommend the galvanized tubular or lattice steel masts.
