Jampro News at NAB 2011

The UHF Superturnstile Batwing Band IV/V 470–860 MHz antenna hosting NTSC and CCIR channels will be one of Jampro's novelties for NAB 2011. Another novelty will be the RWED-516-U, a compact TV mask/filter combiner, which has an associated cross-sectional design to accommodate channels and comply with the strictest filtering standards.

The Jampro UHF Superturnstile Batwing Band IV/V 470–860 MHz antenna hosting NTSC and CCIR channels will be one of the novelties at the show. It features a structure that has been hot-dip galvanized to ensure long-lasting contact and to ensure reliability at important transportation points, thus providing superior value to current broadcasters. High strength beryllium copper with soldered brass terminal material has been used for the fan hoses and all connections have been screwed. Directional butterfly antennas are available as a custom feature and butterfly antenna reconnect kits are optional.

Also new will be the RWED-516-U, a compact TV mask/filter combiner, which has an associated cross-sectional design to house channels and meet the strictest filtering standards, in addition to providing constant impedance performance for adjacent and channel separations greater than 15. The RWED-516-U provides the same high isolation as traditional constant impedance technology and achieves an elliptical response without external coupling mechanisms. Important dies handle high power with low insertion loss; Their filters correspond to temperature compensated ones for applications that are closely spaced. The RWED-516-U can be expanded to accommodate future channels and is not subject to the bandwidth limitations of standard hybrid technology designs.

Por otro lado, la antena de banda ancha Jampro JA/MS-BB UHF Slot, que forma parte de la legendaria línea Prostar, ofrece una “única solución” robusta de alto rendimiento que ha sido exhaustivamente probada para aplicaciones análogas o para DTV broadcast. En comparación con la compra, instalación y mantenimiento de múltiples antenas, el JA/MS-BB es una alternativa asequible. Proporciona una única solución compacta que conserva el espacio de la torre y minimiza la carga del viento. Ha sido específicamente diseñado para operaciones en multi-canal/canal combinado en aplicaciones de TV análoga-análoga, análoga-digital o digital-digital. El JA/MS-BB se suministra ya ajustado de fábrica y esta listo para ser instalado, además de tener un diseño elegante y aerodinámico. Se puede configurar para polarización horizontal, circular o elíptica y dispone de inclinación del haz principal y relleno de nulos; el JA/MS-BB puede manejar potencias que abarcan desde 2 a 10 kW. La impedancia de entrada es de 50 ohms y se puede conseguir un VSWR de 1.1:1 o mejor sobre sub-bandas que abarcan desde 470-530 a 835-890 MHz.
