ORF has Austria's 500-kilowatt short-wave transmitter blown up The whole world can be reached with a unique short-wave antenna from Austria. It could be blown up as early as Thursday.

Frequency-swept input-impedance measurements to determine Q factors and field strengths for an electrically small tuned transmitting loop antenna in its operating environment have recently been made.

In that case, you can replace the sequence of two 4.7kΩ resistors with a single 10kΩ. Now, wire a loop of wire between the open end of the one 4.7kΩ and ground - this loop acts as coupling coil to the ...

They have optimized the way antennas transmitting and receiving power interact with each other, making use of the phenomenon of “radiation suppression.” Through their research, the Aalto team showed ...

Two loop antennas (radius: 3.6 centimeters) can transfer power between each other from 18 centimeters. Image: Nam Ha-Van/Aalto University A better way to wirelessly charge over long distances has been ...

An accurately calibrated and sensitive antenna is needed for such work. This White Paper looks at the characterisation of magnetic loop antennas — those sensitive to the magnetic component of an ...

How do you check if an RF transmitter is working? You should be able to make a small loop antenna ("sniffer") with a UHF diode and capacitor. Connect this to a voltmeter on DC and hold the loop close ...

Current-loop power source: The power - supply V DC voltage varies (9 V DC, 12 V DC, 24 V DC, etc.) depending on the application, with at least 10% higher potential than the voltage drop of the ...

With those fond memories in mind, I purchased a Philips Modern Loop Rabbit Ears Indoor TV Antenna for $12. I placed it by the window, hooked it up to the AirTV Anywhere and reset the local channels.
