TURGI, SWITZERLAND — There are many innovative ways the industry can use shortwave broadcasting to provide secure data transmission and high-speed communications.
The modern world increasingly requires available real-time secure communications between centralized locations and often to many receivers in unknown locations thousands of kilometers away.
[…]Information transfer via the internet or via fiber optic cable was once the reference. However, the use of such technology means that the information is only delivered to fixed points. In addition, the use of third-party infrastructures provides a security risk and increases transport cost.
Today, near-instant communication to unknown, remote receivers using shortwave is being developed as a new secure means of communications without the need for external providers, delivering signals directly to multiple, or even mobile, destinations regardless of fixed infrastructure. Messages may be dispatched much faster, thus for situations where time is critical, each additional second could be profitable and even save lives.[…]
WBCQ The Planet Announces New Showcase Radio Facility
Plymouth Meeting, PA:
WBCQ The Planet announced today that it is building one of the most powerful and versatile radio stations in the world. WBCQ’s new shortwave radio station, now under construction in Monticello, Maine, features a new 500-kilowatt transmitter from Continental Electronics and a state-of-the-art antenna system from Ampegon Antenna of Switzerland.
The new station, funded by private investors, will be able to direct a powerful shortwave signal to any country on Earth. Our new facility is planned to be a showcase for the radio world and is dedicated to our free speech mission.
The new station is planned to commence operations in fall 2018.
Obviously, the investor has deep pockets and I understand is affiliated with a religious organization. The new antenna and transmitter building is being built on land adjacent to the existing transmitter site. WBCQ actually broke ground last summer and the massive antenna’s foundation is already in place. The antenna is on site now, but has not been assembled. Most of the construction is on hold during the winter, but WBCQ plans to have this 500 kW station on the air by Fall 2018.
Ampegon says it is about to deliver and install its first rotatable shortwave high-power array antenna on the North American continent.
The system, which will be installed WBCQ in the United States, is designed for the transmission of shortwave signals of up to 500 kW, the high-power antenna offers different radiation patterns, an antenna gain of up to 23 dB and uses a technology characterized by a single-shaft structural design.
Swiss-based company Ampegon has accepted a contract from Al Rashed to handle the upgrade of five analog shortwave transmitters that are more than 20 years old for the Kuwait Ministry of Information in Al Kabd station.
[…]Ampegon will refurbish all of the transmitters, and in addition upgrade three of them to full digital DRM integration and converted to the new transmitter control system UCS[…]
Ampegon Introduces New Folded Monopole Mediumwave Antenna System
IBC 2015, September 10, Amsterdam. Ampegon, leading supplier of full range mediumwave equipment up to 1200 kW is introducing a folded monopole 50 kW antenna system with new design concept and optimized antenna structure that brings many benefits to broadcasters.
The folded monopole antenna is fully grounded with no need of a base insulator for the placement of the antenna. This is an advantage for the antenna setup; maintenance of components and auxiliary systems installed on the antenna structure is simplified. For example, no isolated energy transformer is required to power the air obstruction light; the light on the antenna structure is supplied directly.
Constructed as a single unit, the folded monopole antenna consists of the mast and the radiating element. The guy ropes supporting the mast are each divided by a single insulator. The upper section forms the “antenna cage”, which is connected to the mast on one side, and by ropes to the insulated feed point at the base of the antenna. As a result, there are no floating potentials in the ropes or in the steel structure, which might cause electrostatic discharges or flashovers. A minimum number of insulators are installed and consequently the maintenance requirements are simplified and minimized. The newest type of insulator used in Ampegon systems features silicon protection and demonstrates an outstanding ruggedness towards environmental influences, such as air pollution.
Ampegon Introduces New Folded Dipole Shortwave Antenna System
IBC 2015, September 11, Amsterdam. Ampegon, leading supplier of shortwave equipment up to 500 kW is setting new standards in antenna construction. A new antenna design concept and an optimized antenna structure is used for the introduction of the single band folded dipole antenna system, available in the RF power range up to 50 kW and developed for economic and efficient domestic shortwave transmission. The 50 kW system is designed with proven and reliable Ampegon components and optimized to low power specifications, which results in significant simplification without any loss of performance.
The antenna system has outstanding key performance indicators like VSWR ? 1.5 in the operational frequency band (Z0 = 300 W) and a gain of 8 dBi.
The highly cost efficient design has tubular structures for suspension of the dipole, no on-site welding is necessary. It is designed for a wind speed of 160 km/h (survival) according to American Standard EIA-222-F with glass fiber reinforced guy ropes for minimal interference with antenna radiation.
