How an Antenna Diplexer Allows for Multiple Broadcasts on One Transmitter
[ad_1] A diplexer, which is a form of duplexer, is a three-port frequency-dependent device used either for transmitting or receiving purposes. It can take different frequency bands and multiplex and de-multiplex two ports and put them onto one port on a single coaxial cable. Or a diplexer can route signals based on frequency that have…
Satellite Communication Overview of the Technology & the Antenna System Part IV
[ad_1] Key Issues Looking ahead of 1990’s, one could observe a very rapid expansion of global market in satellite communication into personal communication and new mobile satellite services, such as Personal Communication System (PCS) and Mobile satellite Services (MSS) respectively, Low Earth Orbit (LEO) satellite systems, Global Positioning System (GPS) navigation, and new direct broadcast…
Common Features and Uses of a Directional Antenna Phasing Cabinet
[ad_1] One of the key components of a directional antenna system, involving a receiving or transmitting aerial device that converts electric power into radio waves and vice versa, is the phasing equipment (aka the phasor cabinet). This system is highly used in directional AM Stations and in the medium wave (AM) frequency band, as it…
