(16=160 MHz, 3-5 elements) Inexpensive lightweight 3 or 5 elements directional antenna with “straight” driven element and “gamma matching” designed for various point to point as well as point/multipoint applications, such as rural telecommunications, repeater operations, telemetry SCADA links, etc. Antenna is made of AD31 (T6063) galvanized aluminium. Feed line connector is UHF female panel mount type mounted on driven element. Antenna is tuned to central frequency of customer specified range (< 8 MHz) or specified frequency.

UHF dipole antennas (45=450MHz 1-8 elements) for extensive range of applications – trunking radio systems, military communications, dispatch base stations, amateur radio repeaters, etc.

5, 9 or 12 elements wide bandwidth light weight directional antenna with folded dipole as driven element designed for various point to point as well as point / multipoint application. Folded driven element incorporates “balun” matching circuit optimized for wide bandwidth and accurate matching. All components of antenna are DCgrounded for better lighting and antistatic protection.
