UHF Omnidirectional Antennas for Small to Medium-Power Sites 6 Gap With the introduction of digital TV broadcasting, these services are now no longer restricted to stationary receivers with roof-top Rx antennas, but also permit portable and mobile reception. However, in order to achieve a satisfactory grade of coverage and to take account of the requirements for higher reference field strengths, gap-filling antennas may be necessary, at least in urban areas and metropoles. Some broadcasters may even wish to design their networks by using multiple small to medium power transmitters, similar to a cellular structure. Kathrein’s portfolio of antennas for these applications includes versions from 400 W to 15 kW, all fully-assembled for plug-and-play installation. They come fully-radomized, thus featuring very low wind-load figures. This makes them especially suitable for DTV and DVB-H gap-filler stations.
