KPH is a coast radio station on the Pacific Coast of the United States. For most of the 20th century, it provided ship to shore communications including telegrams (using Morse code) and marine telex service (using radioteletype). The station discontinued commercial operation in 1998, but is operated occasionally as a historic service – its ...
In the case of an AM broadcasting station (mediumwave and longwave, occasionally shortwave), the multiple mast radiators may all be part of an antenna system for a single station, while for VHF and UHF the site may be under joint management. Alternatively, a single tower with many separate antennas is often called a "candelabra tower". [6]
CBS used shortwave to support its Latin American international network, which consisted of 64 stations located in 18 countries and GE's KGEI opened in San Francisco in 1939, transmitting to Asia. [16] [17] [18] On November 1, 1942, all 14 private U.S. shortwave stations ended commercial operations and were leased to the Voice of America. [19]
The extension also had inductors at the far end, such that each part of the antenna had inductors at its ends. In 1925, the two parts of the antenna were split, each now operating separately (the original as callsign MUU, the 1924 antenna as GLC), a new feed taken up the mountain from the western transmitter buildings to the site of the double ATI.
An ideal “broadband” shortwave antenna would work continuously across much of, if not all of, the shortwave spectrum with good radiation efficiency and minimal compromise of the radiation pattern. Most practical broadband antennas compromise on one of the above: Either they only work on a few relatively narrow slices of the HF radio ...
Before the HRS antenna became the default design for high power broadcasting in the 1950s, Sterba curtains were used to transmit shortwave broadcasts. Sterba curtains are modest-gain single-band curtain array antennas. They are named after Ernest J. Sterba, who developed a simple shortwave curtain array for Bell Labs in the 1930s. [1]

The project countersued under the SLAPP provisions of California law and prevailed in court. [ 9 ] [ 10 ] [ 11 ] [ note 1 ] The lawsuit drew additional public attention to Streisand's home, giving name to the Streisand effect : the phenomenon in which attempting to hide or censor information instead draws greater attention to the information.
