Voltage Standing Wave Ratio (VSWR – sometimes pronounced “Viz-Wer”) or Standing Wave Ratio (SWR) is a measure of how well matched the impedance of the radio (transmitter or receiver) and antenna and transmission line carrying Radio Frequencies (RF). It is …
Most modern MPPT (Maximum Point Power Tracking) smart solar charge controllers use 4-stage battery charging process. Battery life is prolonged and therefore keeping them at optimal performance at all times. Smart Chargers can also protect the battery from being overloaded, …
Power over Ethernet (PoE) combines both data communication and power transmission for remote devices in the one cable, therefore eliminating the need to run a separate cable to power a device. Increasingly used for VOIP phones, wireless access points (WAP’s) …
3-axis stabilized antennas have to be used on maritime vessels for many years to compensate for the ships movement to track a satellite signal. There are 4 main antenna manufacturers that the majority of VSAT (and TVRO) satellite service providers …
Satellite communication is used for internet connection in remote areas of the world where a connection to the traditional copper or fibre network is not possible or used as a backup communication link for mission critical systems. VSAT is an …
When installing coax cable you need to know the distance of the run for the maximum coax cable lengths due to the attenuation of the L band RF signal and voltage drop on the coax cable between the outdoor equipment …
Prior to attempting to point the dish at the satellite you need to pre-set the polarization angle (also called skew) of the RF feed horn assembly. The NOC (Network Operations Center) should be able to tell you what polarization of …
When installing a VSAT satellite equipment you will need to know what polarization is used on the link and you will have to set up the RF feed assembly correctly. Cross-Pol (or XPOL) and Co-Pol are used for linear links. …
Satoms are now offering free online training courses for the Satellite & Communications industries. These courses will provide in-depth technical content, Health & Safety and practical information working in these sectors. The courses will give you the technical knowledge you need …
Ensuring that the coax connectors (F-Type N-Type or BNC etc.) are properly terminated is vitally important if you want reliable communications. Poorly terminated connectors will cost you money, time and reputation. This poorly terminated RG-6 coax was used in a …
