Tower of Power is a 777 ft (236.8 m), 100,000 watt TPO communications tower of GMA Network located in Tandang Sora, Barangay Culiat, Quezon City. It serves as a transmitter facility for flagship stations DZBB-TV 7 and DWLS (Barangay LS) 97.1.[1] The site also has a transmitter facility leased by ZOE Broadcasting Network for its flagship DZOE-TV 11, the originating station of GMA News TV (which GMA has a joint venture with ZOE through its subsidiary Citynet Network Marketing and Productions, Inc.).

History[edit]

The Tower of Power was constructed on a huge vacant lot in the 3rd Quarter of 1987, as a new edifice for the network and for the preparation for Rainbow Satellite broadcast to replace an old surplus 50-kilowatt transmitter located at the old RBS building in EDSA, and to clear TV and FM reception. The tower's construction uses 600 tons of steel from a local steel mill, costing PHP 170 Million pesos for the building of this tower. Antennas are also provided to enhance signal strength. After several months of planning, the tower completed in October 1988 and on November 7, 1988, the tower was opened by then-President Corazon Aquino and the GMA Network board of directors. A grand TV special was started after the inauguration. The slogan GMA-7-POWER was used from November 7 to December 1, 1988 as a station ID.

Features[edit]

The tower[edit]

The Tower of Power uses its high-gain corner reflector antennas to produce a wide coverage of VHF TV reception in Metro Manila, Region 3 (Central Luzon) and 4-A (Calabarzon). It is including Bulacan, Pampanga, Zambales, Tarlac, Bataan, Nueva Ecija, Laguna, Batangas, Cavite, Quezon, Aurora and Rizal in both grades A and B for the broadcasts of DZBB-TV and DZOE-TV.

For FM radio, DWLS's signal strength utilized by a circular bay Jampro FM antenna provides listeners with clear FM reception of 25 kilowatts and to spread out in Metro Manila and nearby provinces as well.

It also serves as a repeater for the transmissions of Channel 27 in Cebu and Davao to relay Channel 11's programmes.

The transmitter facility[edit]

The transmitter facility houses television and FM radio transmitters for DZBB-TV, DZOE-TV and DWLS containing sets of transmitter equipment imported by Harris and RCA of the United States, and JVC of Japan. At the same time, the satellite downlink facility housed all satellite broadcasts directly to the United States and other countries to produce foreign programmes.
