Co-Star’s Latest RF Connectors for Wireless Applications

C23SRP_025SP-RPCo-Star has developed a new range of RF connectors and adapters  for connecting external antennas to Wireless Routers, Mobile Data Terminals (MDT’s) and other wireless devices.

FME Male to TS9 Male Right Angle Adaptor Cable

The TS9 connector is often used across a number of cellular, GSM, 3G and 4G dongles, data cards and modems. Very similar in appearance to the CRC9 connector, the TS9 plug has a  gold plated centre pin and circular barrel with slots at the end. The C74-FP-025TS9RA cable has been designed to quickly & easily  covert an antenna terminated with an FME female which is a common connector used for mobile applications to TS9 without having to re-crimp. Co-Star have used a right angle TS9 connector to ensure secure connection into the wireless device. The cable length is 250mm of RG174 coax.

SMA Male Reverse Polarity to SMA Female AdaptorCF_40

Widely used by Wi-Fi equipment manufacturers RP SMA connectors are designed to prevent consumers from accidently  connecting antennas with gain which would breach compliance. The female RP-SMA connector has the same external housing as a standard or conventional female SMA connector, which consists of an outer shell with the threads on the outside; however, the center receptacle is replaced by a male pin. Similarly, the RP-SMA male has threads on the inside like a conventional male, but has a center receptacle instead of the male pin in the middle.

The CF.40 adaptor has a Reverse Polarity male and standard SMA female to enable engineers to convert a standard SMA male which is a commonly used as standard by antenna manufacturers to SMA Male Reverse Polarity.

SMA Male Reverse Polarity to SMA Female Reverse Polarity

Manufactured using low loss RG58 coaxial cable (250mm) the C23SRP.025SP/RP SMA Male RP to SMA Female RP cable extension can be used to convert the genders of RP SMA connectors on antennas or as a cable extension.

Antennas & Cable Assemblies for improving Smart Meter performance

C23SP-SSmart Meters can be installed in remote areas with limited network coverage so antennas & RF cable assemblies play an integral part in the performance of the Smart Meters in these situations.  Co-Star supply a range of Panorama antennas that offer excellent performance across a wide bandwidth which are designed to improve the network coverage and enable better performance when transferring and monitoring data over the cellular network the performance of the devices.

Good network coverage is vital to the performance of a smart-meter and a good quality antenna can improve the performance  by  maximising the signal strength and enhancing  the LPB-7-27-200x200network coverage.

Co-Star have a specialised range of Panorama antennas for smart meter applications that work across all cellular frequencies including: GSM/2G/3G/4G and have different mounting options to suit the location, environment & type of device.

RF Coaxial Cable Assemblies

Co-Star also manufacture RG58 low loss coaxial cable assemblies used to extend the cables on antennas. These can be supplied in any length and with any combination of connector including: SMA, FME, TNC, N series and even Reverse Polarity connectors. We manufacture these in the UK and can turn them around very quickly so if you have an urgent requirement than please let us know. We can also manufacture cable assemblies using other low loss coaxial cables including LMR400 for applications that require long extensions.

Below are a few different option of the antennas & cable assemblies that we supply but we have many more. Please call or e-mail us for more information: t: +44 (0) 1423 340066 e: sales@co-star.co.uk

What are Reverse Polarity SMA Connectors?

SMA reverse polarity connectors are semi-precision, subminiature connectors that provide repeatable electrical performance from DC to 12.4 GHz with flexible cable. Semi-rigid cabling extends the frequency range to 18 GHz.C30AFRATM

SMA connectors offer broadband performance with low reflection and constant 50 ohm impedance. These features, along with minimum attenuation and low VSWR have made the SMA extremely popular in the microwave community. The SMA design has been broadened to accommodate many interconnection requirements and its design parameters have incorporated the considerations of cost, size, weight and performance to yield the best value in your microwave system. Typical applications include Mobile Data Terminals, Telemetry and M2M applications.

FCC regulations stipulate that wireless devices for spectrum applications with a removable antenna require a non standard antenna connection to prevent accidental connection with standard interface equipment. To conform to this standard the wireless industry developed reverse polarity SMA connectors a male connector having a female pin and a female connector having a male pin. Some manufactures also use a left hand thread connector as the RF port on their equipment which is basically a reverse thread.

Co-Star have a broad range of reverse polarity connectors for RG174 & RG58 coaxial cable as well as adaptors and cable assemblies. If you would like any advice or help on finding the correct connector than please give us a call on: +44 (0) 1423 340066 or e-mail: sales@co-star.co.uk.
