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.

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.

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.

Horwin CB8-V/Ux-x series is low insertion loss combiners with ferrite isolators used for combining several transmitters into one antenna with up to 125 kHz (VHF) and 200 kHz (UHF) frequency spacing. Combiners are configured in sets of 2, 3 or 4 channels. There are two model versions – single or dual ferrite isolators depending on the required Tx–Tx isolation. Nominal impedance is 50 Ohms with typical input SWR <1.5. Mounting option is specified by customer (e.g. “free standing”, vertically or horizontally into EIA 19” etc). N-type “female” connectors are used for input/output connections. Combiners are tuned at customer specified frequencies, so transmit frequencies should be specified when ordering.

“Band pass/reject” duplexer is ideal for repeaters, duplex base stations and other applications when combining of both receive and transmit frequencies into a single antenna is needed. The high Q’s of the filter enable the duplexer to work with narrow duplex spacing and to keep low insertion losses. There are two model versions regarding power handling capability – low power up to 50 watts continuously and high – up to 150 watts. The filter’s cavities are made of extruded aluminium. All coaxial cables used are semi-rigid silver plated. Cables and connectors are with PTFE insulation. Filters are covered with black polymer powdered coating. Each filter is individually made and tuned, so receive and transmit frequencies should be specified when ordering.
