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.

WMUR-TV Says FAA Drone Rules Preclude ENG
The FAA’s current rules and proposed ban on flight over people, requirement of visual line of sight and restriction on nighttime flying, effectively prohibit broadcasters from using UAS for newsgathering. ~ WMUR-TV General Manager Jeff Bartlett
