KRTV (Arkansas)
KRTV was a television station on ultra high frequency (UHF) channel 17 in Little Rock, Arkansas, United States. The first television station in Arkansas, KRTV operated from April 1953 to March 1954. Its early demise was attributed to economic factors that made it impossible to compete with competing very high frequency (VHF) stations that signed on after KRTV. One of these stations, KATV (channel 7, then located in Pine Bluff, Arkansas, Pine Bluff), purchased KRTV's studio facility and assumed its personnel, a prelude to KATV itself moving to Little Rock in 1958. History Little Rock Telecasters, a company half-owned by newspaper man Donald W. Reynolds and half by other investors from Texas (E. H. Rowley of Dallas and Kenyon Brown of Wichita Falls, Texas, Wichita Falls), applied for a construction permit to build a UHF television station in the city in August 1952. A construction permit, the first in the state of Arkansas, was granted on September 18, 1952. By December, the Prospect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
