ERI details NAB exhibits


ERI / Electonics Research,Inc.Electronics Research, Inc. will exhibit a variety of new and existing products from their line of broadcast antennas, transmission line, filters and combiners, and towers from booth C22612 at NABSHOW 2013 at the Las Vegas Convention Center, April 8-11.


ERI Launches Enhanced 788 Series ALLPASS™ Diplexer

The new 788 Series ALLPASS™ high power HD Radio FM analog/IBOC diplexer features increased power handling to 49 kW and a more compact design for a substantially reduced footprint. ERI’s innovative ALLPASS design allows stations to operate digitally at powers up to -10 dBc. This ALLPASS diplexer maintains high efficiency while minimizing group delay and insertion loss compared to other available methods.

ERI Introduces 995 Series Constant Impedance Ganged Circulator System:

The 995 Series addresses the need for additional isolation in dual input FM antennas and combining systems with its Ganged FM Circulator System. The Ganged Circulator is available to provide additional isolation for either analog or digital FM transmitters with power output levels up to 80 kW. The most popular are the model 995-5; which handles up to 5 kW of power, analog or digital, and the model 995-3; which handles up to 3 kW of power, analog or digital, for a single FM channel.

The 1190 Series FM Panel Antenna:

A new circularly polarized FM panel antenna for directional and non-directional applications. The 1190 is constructed from galvanized and stainless steel and is intended to be used in single frequency FM applications, on large faced towers for directional and omnidirectional requirements. The individual 1190 elements are rated to handle up to 18 kW of input power and include an integrated hybrid power divider so each element requires only a single transmission line.

New Low Power UHF Filter

The CF2001 Series low power UHF band pass mask filter is a 1.5 kW filter, constructed of lightweight aluminum, is temperature stable with a pseudo elliptic response and compact in size. The filter is available in 6 pole and 8 pole versions and can be tuned for compliance with “full service” and “stringent” mask requirements. The CF2001 Series comes standard with 1-5/8 inch 50 ohm EIA connectors. Optionally, 7-16 DIN connectors are also available.

ERI Expands AL Series Low Power UHF Antennas

They’ve expanded the AL Series UHF television antenna product line to include 2, 4, and 6 gain models, in addition to the popular AL8 model. The antennae are available in versions for horizontal, elliptical, and circular polarization. The AL Series antennas are available with omnidirectional, Omnioid, and cardioid azimuth patterns and handle up to 2 kW, average power.
