An avalanche transceiver or avalanche beacon is a type of emergency locator beacon, a radio transceiver (a transmitter and receiver in one unit) operating at 457 kHz for the purpose of finding people buried under snow. They are widely carried by skiers, particularly back country skiers for use in case a skier is buried by an avalanche.
Avalanche Transceivers — known as beacons, "beepers", peeps (pieps), ARVAs (Appareil de Recherche de Victimes en Avalanche, in French), LVS (Lawinen-Verschütteten-Suchgerät, Swiss German), or various other trade names, are important for every member of the party. They emit a "beep" via 457 kHz radio signal in normal use, but may be switched ...
The antenna feed system or antenna feed is the cable or conductor, and other associated equipment, which connects the transmitter or receiver with the antenna and makes the two devices compatible. [ 1 ] [ 2 ] In a radio transmitter, the transmitter generates an alternating current of radio frequency , and the feed system feeds the current to ...
The company also offers avalanche transceivers under the Barryvox brand. [27] In addition to the main Mammut brand, the Mammut Sports Group also included Ajungilak (sleeping bags), Lucido (headlamps) and Raichle (shoes) as independent brands. The company now only carries Mammut as its main brand (for example, Raichle was discontinued around ...
Viewing of the pin and the horn antenna in a low-noise block downconverter. The LNB gets its power from the receiver or set-top box, using the same coaxial cable that carries signals from the LNB to the receiver. This phantom power travels to the LNB; opposite to the signals from the LNB.
In the Direct conversion receiver, the signals from the antenna are only tuned by a single tuned circuit before entering a mixer where they are mixed with a signal from a local oscillator which is tuned to the carrier wave frequency of the transmitted signal. This is unlike the superheterodyne design, where the local oscillator is at an offset ...
In radio communication, a transceiver is an electronic device which is a combination of a radio transmitter and a receiver, hence the name.It can both transmit and receive radio waves using an antenna, for communication purposes.
A horn antenna has a flaring metal horn attached to a waveguide. It is a simple antenna with moderate gain of 15 to 25 dBi, used for applications such as radar guns, radiometers, and as feed antennas for parabolic dishes. Slot Consists of a waveguide with one or more slots cut in it to emit the microwaves. Linear slot antennas emit narrow fan ...
