Dielectric to debut two MobileMedia products at NAB

The new 1.4GHz Antenna and 1.8kW Switchback Filter unite performance and efficiency for mobile broadcasting

At NAB2009, Dielectric will unveil the two newest members of its MobileMedia product family: the 1.4GHz Antenna for L-band applications and the 1.8kW Switchback Filter for 700MHz applications.

Dielectric's new 1.4GHz Antenna delivers a new variation of the company's pylon-style broadcast antennas. Dielectric's L-band, high-power, circularly polarized, broadband antenna features both azimuth and elevation pattern versatility in a single low-wind-load mechanical package. The antenna can be either side- or top-mounted to provide an excellent axial ratio, a 1kW-4kW input power rating, gains of 15dBi-19 dBi, a VSWR of less than 1.1:1 and 10kW-24kW ERP/polarization.

The Dielectric 1.8kW Switchback Filter is designed specifically for 700MHz applications. With a compact rack-mountable package, the filter delivers high electrical performance with less than 1.1dB integrated insertion loss. State-of-the-art material selection provides temperature compensation within +/-10kHz and an overall temperature range of 0-45 degrees Centigrade. The filter supports a 2000W power capability and provides a VSWR of less than 1.25:1.
