Twin Peaks (San Francisco)
The Twin Peaks are two prominent hills with an elevation of about located near the geographic center of San Francisco, California. The Twin Peaks are the second and third highest natural points in San Francisco; only Mount Davidson is higher within city limits.San Francisco Recreation and Parks Department (2006)"Twin Peaks", section 6.8 o''Significant Natural Resources Areas Management Plan''. Retrieved April 21, 2007. Location and climate Twin Peaks, along with Mount Davidson and Mount Sutro, create a rugged landscape in the center of San Francisco which influences microclimates in the city. The mountain acts as a natural barrier against summer fog for the city's eastern neighborhoods. The North and South Twin Peaks, also known as "Eureka" and "Noe", are about apart. The peaks form a divide for the summer coastal fog pushed in from the Pacific Ocean. Their west-facing slopes often get fog and strong winds, while the east-facing slopes receive more sun and warmth.

Effective Radiated Power
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength or power flux density in watts per square meter) as the actual source antenna at a distant receiver located in the direction of the antenna's strongest beam (main lobe). ERP measures the combination of the power emitted by the transmitter and the ability of the antenna to direct that power in a given direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It is used in electronics and telecommunications, particularly in broadcasting to quantify the apparent power of a broadcasting station experienced by listeners in its reception area. An alternate parameter that measures the same thing is eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna (radio), antenna with the purpose of signal transmission to a radio receiver. The transmitter itself generates a radio frequency alternating current, which is applied to the Antenna (radio), antenna. When excited by this alternating current, the antenna Electromagnetic radiation, radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio communication, radio, such as radio broadcasting, radio (audio) and television broadcasting stations, cell phones, walkie-talkies, Wireless LAN, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Masts And Towers
Radio masts and towers are typically tall structures designed to support antenna (radio), antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. A mast radiator or radiating tower is one in which the metal mast or tower itself is energized and functions as the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a Guyed mast, mast is held up by stays or guy-wires. ; A ''mast'': is a guyed mast, a thin structure without the shear strength to stand unsupported, that uses attached guy lines for stability. They may be mounted on the ground or on top of buildings. Typical ''masts'' are of steel latt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
