The high-power transmitter ceased sending signals on October 5, 1958.

Over the next 20 years, transistors replaced tubes almost completely except for high-power transmitters.

For example, touching or standing around an antenna while a high-power transmitter is in operation can cause severe burns.

At high-power transmitters, cage lines are used.

In broadcast engineering, a desiccator may be used to pressurize the feedline of a high-power transmitter.

High-power transmitters may have additional constraints with respect to radiation safety, generation of X-rays, and protection from high voltages.

The high-power transmitter consists of two 500-kW transmitters operating in parallel and feeding a north-south linear array 10,560 feet long.

Add a high-power transmitter to the mix and now you need much higher-quality filters (15 db/octave?)

Mercury batteries powered the high-power transmitter for 31 days and the low-power transmitter for 105 days.

Legal (short-range) use of CB radio is sometimes impeded by users of illegal high-power transmitters, which can be heard hundreds of miles away.

Very pure deionized water, due to its relatively low electrical conductivity, is used to cool some electrical equipment, often high-power transmitters and high-power vacuum tubes.

At 13:10 the German bombers were within 40 miles of the BBC high-power transmitter at Hatfield, Hertfordshire.

The station's original high-power transmitter was a Western Electric 10KW that had previously been installed at KNX-FM.

However, the geography of Germany prevented this - despite placing high-power transmitters in border areas, the GDR could not penetrate the whole of West Germany.

Since a traditional car phone uses a high-power transmitter and external antenna, it is ideal for rural or undeveloped areas where mobile handsets may not work well or at all.

The Marconi Company built a Long Wave receiver station in Tywyn in 1914, working in duplex with the high-power transmitter station near Waunfawr.

It said activities to be sold include Continental Electronics in Dallas and TVT Ltd. in Cambridge, England, makers of high-power transmitters for broadcasting.

Included was a radio facility with a high-power transmitter (call letters WUR) for Morse-code communications, Most of the buildings were Spanish Colonial Revival architecture in style.

In many ways, this system duplicates the function of the Jicamarca radar except that it does not use the main high-power transmitters, which are expensive and labor intensive to operate and maintain.

The duplexer is a device which prevents the repeater's high-power transmitter (on the output frequency) from drowning out the users' signal on the repeater receiver (on the input frequency).

This phase of upgrade of the 60 kHz broadcast service involved development of a second, identical, transmitting system including a reconditioned low-frequency antenna and associated helix house, new transmission line, and high-power transmitter.

During the afternoons, Fayetteville station WRCQ often bleeds over into WCOM-LP's radio space, due to WRCQ's high-power transmitter being fairly close by (about 60 miles).

Border blaster stations in northern Mexico also used this effect, along with very high-power transmitters, to extend their nighttine broadcast ranges well over the US/Mexico border and across most of the United States.

As very tall radio towers of any construction type are prominent landmarks, requiring careful planning and construction, and high-power transmitters especially in the long- and medium-wave ranges can be received over long distances, such facilities were often mentioned in propaganda.

Simon (1980) - A psychology professor, brainwashed by scientists as a prank to believe he is of extraterrestrial origin, attempts to reform American society by broadcasting his pronouncements with a high-power transmitter that overrides TV network feeds, becoming a national celebrity in the process.
