(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.

Heavy duty 3 or 5 elements directional antenna with folded dipole as driven element designed for various point to point as well as point/multipoint application when wide bandwidth, mechanical strength and durability are important. 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.

Horwin CH-V/Ux-x series is a hybrid combiners with ferrite isolators used for combining several VHF/UHF transmitters into one antenna with close frequency spacing. Combiners are configured in sets of 2 or 4 channels. There are two model versions – single or dual ferrite isolators depending on the required Tx – Tx isolation and (or): low power– up to 50 watts and high – up to 100.Nominal impedance is 50 Ohms. N-type “female” connectors are used for input/output connections. Combiners are mounted on standard EIA 19” panel 3 U high and 355 mm depth. Combiners are tuned at customer specified frequencies, so transmit frequencies should be specified when ordering.
