Frequencies Supported

Ultra High Frequency (UHF): 300-3000 MHz

This is currently the most commonly used frequency band. The linearity of UHF is still higher than VHF, but this bandwidth can carry even more data and, given its adaptability to compact antennas and receivers, it finds wide use in mobile telephones, digital terrestrial broadcasting, police radios, taxi radios, aircraft and weather radar, ham radio, and so on.

Mobile Communications Base Stations

From the fabrication of antennas, steel towers, and peripheral equipment to aftermarket services, DKK has a full line of products and services for the base stations used as relay facilities for mobile communications of cellular telephones and the like.

Television Broadcasting Transmission Stations (Relay Stations)

Broadcasting is done via relay stations for areas that cannot receive broadcast signals for master stations. DKK will survey the area to be served by the relay station, providing an end-to-end service that includes antenna fabrication, installation, and on-site tuning, as well as steel tower strength assessment and design, fabrication, and maintenance.
