Jampro to Show Versatile TV Mask-Filter Combiner at IBC
Jampro Antennas, a Sacramento, Calif.-based provider of advanced antennas and RF equipment, will showcase its array of DTV products at IBC.
The UHF RWED-516-U compact TV mask/filter combiner with four-port directionality can be used as either a mask filter or constant impedance-combining module for high power UHF TV broadcasts. The unit features a cross-coupled design to accommodate adjacent channels, meets stringent filtering standards and provides constant impedance performance for adjacent and channel separations greater than 15. The RWED-516-U provides the high isolation of traditional constant impedance technology and achieves elliptical response without external coupling mechanisms. Large cavities handle high power with low insertion loss; its filters are temperature compensated for closely spaced applications.
Jampro will also feature its JA/MS-BB Broadband UHF Slot antenna that provides an economical alternative to buying, installing and maintaining multiple antennas. The most recent addition to the company’s Prostar line, the JA/MS-BB provides a single, compact solution that conserves tower space and minimizes wind loading. It’s especially designed for multichannel/combined channel operations in analog-analog, analog-digital or digital-digital TV applications. Broadcasters can choose from a selection of standard and custom transmission patterns. It can be configured for horizontal, circular or elliptical polarization, beam tilt and null fill are available; the JA/MS-BB handles power ranging from 2 to 10 kW. Input impedance is 50 ohm and VSWR of 1.1:1 or better can be achieved over sub-bands ranging from 470-530 to 835-890 MHz.
Jampro will also show its compact RCCC Mask Filter/Combiner for DVB-T & DTV featuring convection cooling and temperature compensation, high-isolation and low-insertion-loss, and the JL-SS Super Slot low-power TV Antenna series.
