The RFI YB16-71 is a 16-element Yagi antenna built for high-gain directional communication in the 470–490 MHz frequency range. It is designed for applications requiring focused signal transmission and minimal interference.
These crossband couplers are ideal for low and medium power applications requiring 66-88 MHz or FM Broadcast 88-108 MHz to be combined with VHF Hiband 144-174 MHz. Typical applications include the combining or separating of signals for use with dual band mobile radios or antennas, or for signal distribution systems including Bi- Directional Amplifiers (BDAs) and Radiating Cable systems.
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 are recommended. To ensure that you choose the correct phasing harness for your application, please use the following matrix.

The RFI YH02 is a 2-element Yagi antenna designed for directional communication across the 100–250 MHz frequency range. With a gain of 5 dBi, it is ideal for applications requiring focused signal transmission and controlled radiation patterns.
The RFI YB6-61 is a 6-element high-gain Yagi antenna designed for directional communication in the 450–480 MHz frequency range. With a gain of 11 dBi, it is ideal for RF control, point-to-point links, and other applications requiring focused signal transmission and minimal interference.
This Antenna Model HPM-RM-077083 is a helical roof-mount VHF antenna, supply factory tuned to cover 77 to 82 MHz frequency band at a VSWR of less than 1.8:1. Antenna gain is -3 dBq. The lower section of the antenna is a moulded former while the upper section is a helically wound stainless steel section providing a flexible antenna suitable for height restricted areas.
These high gain base station antennas cover the 477MHz band and are ideal for extending radio coverage of your UHF CB radio.
Both these antennas are designed around RFI’s leading patented Meander™ PCB technology incorporating excellent gain, pattern stability, and light weight construction, making these antennas a perfect fit for any base station installation.
The COL5000 comes with integrated N female connector.
RFI 3-Port Directional Couplers are used in a variety of RF combining, sampling and power splitting applications, typically used in DAS (Distributed Antenna Systems) for sampling RF for fibre fed systems and distributing power throughout feeder cable networks. Using directional couplers suitable for covering UHF to high end cellular frequencies saves on the cost of upgrades when public safety radio coverage may have to be accommodated on a DAS designed for cellular coverage. The RFI multiband directional couplers are available in a range of coupling values which gives the network designers and planners the ability to optimise and balance RF levels throughout a DAS network.

The RFI YBS806-82 is a 6-element stainless steel Yagi antenna designed for high-gain directional communication across the 850–960 MHz frequency range. With all-welded 316-grade stainless steel construction, this antenna is built to perform reliably in extreme and corrosive environments while maintaining low PIM and high signal integrity.
The RFI YB806-94 is a high-performance 6-element Yagi antenna designed for directional communication in the 890–960 MHz frequency range. It delivers 11 dBi of gain and is ideal for RF control, point-to-point, and point-to-multipoint applications.
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.

RF Loads and Terminations are used to terminate coaxial cables, multicoupling devices and with test equipment. RF Terminating Loads are primarily used in multi-coupling, distributed antenna, radiating cable systems and laboratory test environments. These 50 Ohm terminations are specifically designed to terminate unused ports on low power devices (such as receiver distribution systems) and help ensure optimum shielding and the lowest system noise figures. RFI has a wide range of coaxial 50 Ohm resistive termination loads in various connector types, power ratings and frequency range DC - 2500 MHz. The heat-sinks have a high thermal density and their surface area is cooled using natural convection.
The RFI YB9-61 is a 9-element high-gain Yagi antenna designed for directional communication in the 450–480 MHz frequency range. With a gain of 13 dBi, it is ideal for RF control, point-to-point links, and other applications requiring focused signal transmission and minimal interference.
RFI UHF Hand Portable Antenna HPA-4752-SMAF, designed for 470-520 MHz frequency range with SMA(F) connector. It is factory tuned for ease of installation.

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.
