Which inventor invented a railroad car coupler nicknamed jenny coupler?
Andrew Jackson Beard
What is the purpose of 50 ohms antenna?
A; it is to match the cable line impedance to the receiver for maximum transfer of energy
What is a reconfigurable antenna?
an antenna that is able to be formed, or bent
Can you replace an XM radio antenna with any other antenna like a 3ft hard cb antenna?
You can replace an XM radio antenna with a CB antenna, a ham 40-meter mobile antenna, a cellphone antenna, a GPS antenna, a TV antenna, a wire coat hanger, a 6 GHz microwave antenna, or a chain of paperclips. However, since none of them is optimized to operate at the frequencies of XM radio, like the XM antenna is, none of the others will work as well. Most of them will likely be so inefficient at the satellite radio frequencies that when you use one of those, you hear nothing at all on your radio.
What did Eli H Janney invent?
The Janney coupler was named after Eli H. Janney who patented the invention in 1873. The Janney coupler was an improvement in railroad car couplers that became the standard for the railroad freightcar couplers.
Where use antena coupler in aircraft?
An antenna coupler is usually placed at the base of the vertical stabilizer to connect the antenna at the leading edge of the stabilizer to the rest of the system.
What is the purpose of a directional coupler?
A directional coupler is a passive device used in radio technology. The purpose of a directional coupler is to couple electromagnetic power to be used in another circuit.
Why is compressed air bad for an antenna coupler?
Compressed air usually is not filter and this could introduce impurities into the coupler system resulting in arching.
What is the purpose of antenna on a radio or TV set?
The purpose of an antenna on a radio or tv set is so that it can get signal so we can view tv or listen to the radio
What is an Antenna Coupler?
For every frequency there is an antenna that is perfect for radiating at that frequency. Unfortunately, it would be unrealistic to carry a separate antenna for every frequency that a communications center is capable of radiating. To overcome this problem, we use ANTENNA TUNING to lengthen and shorten antennas ELECTRICALLY to better match the frequency on which we want to transmit. Simply put, the antenna does not physically change length; instead, it is adapted electrically to the output frequency of the transmitter and "appears" to change its physical length. Antenna tuning is done by using antenna couplers.
What is the purpose of a satellite antenna?
A satellite antenna has one very important purpose. It is designed to allow a home to receive a satellite signal, which then allows users to receive a television signal.
What is 3dB coupler?
50% Coupler :D
What is the purpose of bus coupler for the LT panel?
The bus coupler is used to couple one bus to the other without interruption in power supply. It uses the help of the circuit breaker and isolators to achieve this without creating hazardous arcs.
What purpose does an antenna serve?
An insects antenna serves the purpose of sensing things such as sound, heat and touch, among others. Antennas in telecommunications are used to intercept signals from over the air wavelengths.
What is a coupler?
buc coupler is division between sections, for example if you have a line up of 10 panels, and it is divided into sections, so for mentnance purpose you won't required to shut down the whole up, if you would bus coupler. you can switch off the buscoupler and incomer of one side, and can done the maintenance at one without doing a complete shut down.
Are beer keg taps universal?
No, there are 6 different tapping mechanisms. the US Sankey the European Sankey the Bass Ale Coupler the German Coupler the Guinness Coupler and the M-System Coupler
What is a bus coupler?
buc coupler is division between sections, for example if you have a line up of 10 panels, and it is divided into sections, so for mentnance purpose you won't required to shut down the whole up, if you would bus coupler. you can switch off the buscoupler and incomer of one side, and can done the maintenance at one without doing a complete shut down.
