The Mühlacker Broadcasting Transmission Facility is a radio transmission facility near Mühlacker, Germany, first put into service on November 21, 1930. It uses two guyed steel tube masts as aerials and one guyed steel framework mast, which are insulated against ground. It has two transmission aerials for shortwave and one free standing steel framework tower for directional radio services. The shortwave transmitter was shut off on October 19, 2004. The medium wave transmitter was switched off in January 2012.
Grimeton Radio Station in southern Sweden, close to Varberg in Halland, is an early longwave transatlantic wireless telegraphy station built in 1922–1924, that has been preserved as a historical site. From the 1920s through the 1940s it was used to transmit telegram traffic by Morse code to North America and other countries, and during World War II was Sweden's only telecommunication link with the rest of the world. It is the only remaining example of an early pre-electronic radio transmitter technology called an Alexanderson alternator. It was added to the UNESCO World Heritage List in 2004, with the statement: "Grimeton Radio Station, Varberg is an outstanding monument representing the process of development of communication technology in the period following the First World War." The radio station is also an anchor site for the European Route of Industrial Heritage. The transmitter is still in operational condition, and each year on a day called Alexanderson Day is started up and transmits brief Morse code test transmissions, which can be received all over Europe.
The Eifel Transmitter is an FM and TV transmission facility for the German broadcasting company of SWR and is located on the Scharteberg near Kirchweiler, Germany. Until 1985, the Scharteberg transmitter used a 160 metre tall guyed mast. However this mast did not allow good reception in deep valleys, so in 1985 a new, 302 metre tall, guyed, steel framework mast was built, becoming the tallest structure of Rhineland-Palatinate. The elements of this mast were built by the firm of Hein, Lehmann AG, whilst construction work was carried out by BBS AG, Ludwigshafen. The first 20 metres of the mast were built using a small crane. The mast elements in heights between 20 and 100 metres were mounted by the aid of a car crane, while for the sections above a derrick crane was used. The new mast of Scharteberg transmitter consists of a 288 metre tall, guyed, lattice, steel structure with a square cross section, a side length of 2.1 metres and a 14 metre long GFK-cylinder on top for the UHF antenna. The total weight of the structure is 204 tons. The mast is guyed at 4 levels, 57, 123, 195 and 273 metres above ground. It is equipped with an elevator which runs up to a height of 281 metres. For aircraft warning 20 red neon lamps and two blinking lights with 1000 watt lamps are installed.
The Żórawina radio transmitter is a facility for FM transmission at Żórawina, south of Wrocław. It was established in 1932 as "Reichssender Breslau" and used as an antenna tower. Originally it was a 140-metre-tall free-standing lattice tower built of wood, on which a wire antenna was hung up. On the top of the tower there was an octagonal ring of bronze with a diameter of 10.6 metres for electrical lengthening of the antenna.
NSS Annapolis, officially known as Naval Communications Station Washington, D.C. Transmitter or NavCommStaWashingtonDC(T), was a Very Low Frequency (VLF) and High Frequency (HF) transmitter station operated by the United States Navy.
The Wavre radio transmitter is a facility for Fm, Dab+ and TV broadcasting near Wavre in Belgium. Formerly the mediumwave transmissions used a grounded 250-metre-high guyed mast. Furthermore, there was a backup mast for medium wave transmissions, which was 90 metres high. For shortwave broadcasting there were several directional antennas and a curtain antenna.
HCJB, "The Voice of the Andes", was the first radio station with daily programming in Ecuador and the first Christian missionary radio station in the world. The station was founded in 1931 by Clarence W. Jones, Reuben Larson, and D. Stuart Clark. HCJB now focuses on Ecuador with unified programming on FM at 89.3 MHz in Pichincha, at 92.5 MHz in Manabí, at 96.1 MHz in Tungurahua and Cotopaxi, at 98.3 MHz in Esmeraldas and with separate programming on AM at 690 kHz. Broadcasts in Spanish and indigenous languages on 6.05 MHz (1 kW), continue on an intermittent basis with a new solid state transmitter which in 2017 replaced an older (5 kW) transmitter. These broadcasts were not listed on the HCJB English website as of February 2016.
Radio masts and towers are typically tall structures designed to support 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.
KCBQ is a commercial AM radio station in San Diego, California. It is owned by Salem Media Group and airs a talk radio format. Studios and offices are on Towne Center Drive in San Diego's University City area. The transmitter is off Moreno Avenue in Lakeside, California. By day, KCBQ operates at 50,000 watts, the maximum power for American AM stations. Because KCBQ is not a clear-channel station, it must reduce its power at night to 2900 watts to avoid interfering with Class A stations KTSB in Tulsa, Oklahoma and WWVA in Wheeling, West Virginia, both clear-channel stations. KCBQ uses a directional antenna at all times.
WRMI is a shortwave radio station broadcasting from Okeechobee, Florida, United States. WRMI is a commercial radio station that sells airtime to businesses and organizations.
WRNO is a commercial shortwave radio station which began international broadcasting on February 18, 1982 and continued regular broadcasting through the early 1990s from Metairie, Louisiana, with a continuation of periodic broadcasts starting in 2009. These call letters are still in use by the New Orleans station WRNO-FM; both were founded and originally owned by Joseph Costello III.

The Turner Broadcasting tower was a 314.3-meter (1,031 ft) free-standing lattice tower in Atlanta, Georgia. It was located next to the Downtown Connector between Spring, West Peachtree, 10th and 12th Streets in Midtown. The tower had a triangular cross-section and was built on the site of a previous four-sided broadcast tower built for WAGA-TV 5 and to serve WJRJ-TV which was founded by Rice Broadcasting Inc. which was owned by a local Atlanta entrepreneur, Jack M. Rice, Jr. It is the tallest freestanding structure to ever be voluntarily removed in the United States and second tallest in the world.
Curtain arrays are a class of large multielement directional radio transmitting wire antennas, used in the shortwave radio bands. They are a type of reflective array antenna, consisting of multiple wire dipole antennas, suspended in a vertical plane, often in front of a "curtain" reflector made of a flat vertical screen of many long parallel wires. These are suspended by support wires strung between pairs of tall steel towers, up to 90 m high. They are used for long-distance skywave transmission; they transmit a beam of radio waves at a shallow angle into the sky just above the horizon, which is reflected by the ionosphere back to Earth beyond the horizon. Curtain antennas are mostly used by international short wave radio stations to broadcast to large areas at transcontinental distances.
PCJJ was a pioneering shortwave radio station in the Netherlands operated by Philips Radio on behalf of Philips Laboratories, a division of Philips Electronics. It was the first shortwave radio station in Europe, and the first dedicated shortwave radio station in the world - previous stations had simulcast AM/medium wave broadcasts.
The Palatine Transmitter was the first broadcasting station in Kaiserslautern, Rhineland-Palatinate, Germany. It was built in 1926 and used an antenna, which was spun between two 60 m tall free-standing lattice towers, 130 m apart. The towers were made of wood and were the tallest wooden structures ever built in Palatine.
