Trapped Dipole Antenna
The Hilomast Trapped-Wire Dipole Antenna is a compact and simply-operated multi-frequency antenna, designed to provide up to 6 spot frequencies (dependent upon channel spacing) with bi- or omni-directional coverage in the HF band. The antenna may be used as shown, with two support units (preferred method) or more economically using a single support structure.
The construction reflects Hilomast, LLC’s policy of ensuring long trouble-free use, utilizing only best quality components. Each antenna is supplied complete with 30m of low loss coaxial feeder incorporating a strain-relief arrangement, and fitted with one PL259 UHF connector.
The Dipole Center Junction is formed by a balun unit to ensure matching is achieved.
The elements are constructed of hard-drawn copper magnesium multi-strand for durability and high-resistance to corrosion.
