... In general, this real part, or resistance, consists of the RADIATION RESISTANCE (Rrad) and the LOSS RESISTANCE (Rloss). The radiation resistance is a ‘fictitious’ resistance that would dissipate the same power as the antenna radiates. When the dipole is half a wavelength long electrically, the input ...

Since the path for the loop goes through a set of contacts which are normally open (when the relay is restored they are open, when the relay is energized they are closed), when the loop opens, even momentarily, the relay will drop out and stay that way. A second set of contacts on the relay, normall ...

Valve RF amplifier



A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
