Explore VHF and UHF communication solutions including antennas, filters, amplifiers, and couplers. Ideal for broadcasting, emergency services, and industrial use.
The GP Series is a range of omnidirectional unity gain adjustable ground plane antennas ideal for local area coverage when a high gain antenna is not required or justified. The broad vertical beamwidth offers excellent null fill for consistent signal coverage. GP Series antennas are easily tuned in the field by adjusting the position of the ground plane elements.
The TP Series cavity combiners are ideally suited to combining multiple transmitters in analogue and digital communications systems. Unlike star' or parallel' harnessed cavity combiners, this user-friendly architecture provides a broadband solution allows services to be combined across the entire bandwidth of the antenna. The future expansion of the combiner can be easily performed in-the-field, without retuning or returning the combiner to the factory. The flexibility of the TP Series also caters for other combiner designs requiring multiple transmit, receive, and or transmit/receive frequencies operating in simplex, half duplex, or full duplex configurations. These may be implemented using either separate transmit and receive antennas, or single antenna systems.

RFI UHF Preselector Bandpass Filter is a high-performance RF filter designed for UHF applications within the 450-470 MHz range. This compact milled aluminium filter block ensures low insertion loss, sharp skirt selectivity, and excellent frequency stability. Its 2RU 19"rack-mountable front panel provides easy integration into existing RF infrastructure.
RFI PHE44-99 phasing harnesses are for use in feeding multiple antennas from a single input. These are impedance matching harnesses of coaxial cable construction which can be used in a large variety of applications.
Note: For ALL applications using side mounted dipole antennas, the standard PH Series are recommended. To ensure that you choose the correct phasing harness for your application.
PH and PHE Series phasing harnesses are for use in feeding multiple antennas from a single input. These are impedance matching harnesses of coaxial cable construction which can be used in a large variety of applications.
Note: For all applications using side-mounted dipole antennas, the standard PH Series is recommended. For larger Yagi antennas with extended spacing, consider the PHE Series.
Crossband couplers allow the combining of multiple frequency bands onto shared coaxial and radiating cables and multi-band antennas. Models are available for specialised transmit and receive applications across the frequency range 0.5 - 2500 MHz and beyond. Cascading units can allow any number of different frequency bands to be combined together.
RFI Power Dividers / Combiners are used in a variety of RF power dividing and combining applications. Designed using Wilkinson or N-way styled cascaded broadband binary power splitting or combining techniques offering broadband capability with good splitter output / combiner input, port-to-port isolation. Manufactured using a robust low profiled solid milled aluminium housing these products are ideal for use in coaxial cable networks and multicoupling applications.
RF Terminations are used to properly terminate active RF devices, coaxial cables, unused ports, multi-coupling devices and with test equipment.
RFI loads are normally horizontally mounted and air-cooled by unobstructed natural convection.
The RFI YB9-62 is a 9-element Yagi antenna offering 13 dBi gain for directional communication in the 480-520 MHz frequency range. It is built for high-performance RF applications requiring narrow beamwidth and minimal interference.
SMD4-99 is a specific frequency version of the SMD4. This antenna is designed only for use as a single dipole, not as a component of a phased dipole array as the antenna is custom made to user specified frequencies and is not specifically matched to a phasing harness
The SMD4 series are a range of unity gain side mounted dipoles which can be used as a single antenna for short range applications or, if desired, phased together to provide high gain array coverage characteristics.
The SMD2 Series side mounted dipoles are broad band antennas which, through different phasing and mounting arrangements can offer a variety of patterns (generally cardioid) tailored to specific coverage requirements. These antennas can be mounted in dual arrays for 3 dB gain, or four-stack arrays for 6 dB gain over a single dipole.

The 144-175 MHz COL range is a series of "cut to frequency" 3 dBd gain vertical collinears. The range includes antennas suitable for simplex, duplex and rugged applications. All of the antennas include internal DC grounding for lightning protection and the reduction of static noise. Drainage vents at the base allow the antennas to 'breathe' and thus prevent condensation build up. The alodine finish of the aluminium mounting tube provides a conductive surface which ensures effective earthing when mounted.
