PROVIDING UNIFORM GAIN, LOW VSWR AND A BROAD

FREQUENCY RANGE, EMCO's

three models of Double-Ridged

Waveguide Horn Antennas are ideally suited for IEC 61000-4-3
and MIL-STD 461E immunity tests and ANSI C63.4 and
EN 55022 emissions testing.

As a set, these linearly polarized broadband antennas have an
average VSWR of less than 1.6 to 1 and cover a multi-octave
bandwidth of 200 MHz to 40 GHz. These antennas are
specifically designed for EMI measurements, but can also be
used for EW, antenna gain and pattern measurement,
surveillance, and other applications.

The mounting brackets for Models 3115 and 3116 are adjust-
able for changing polarization of the antenna. Standard
1/4 in x 20 threads are used on the mounting brackets of all
double-ridge waveguides for mounting on an EMCO tripod or
most other tripods.

EMCO Double-Ridged Waveguide Horn Features

Uniform Gain

All models have uniform gain throughout their frequency
span, providing efficient performance characteristics and
directionality.

Power Handling

Model 3106 can handle 1600 W peak and 800 W continuously.

Low VSWR

EMCO’s double-ridged waveguides have an average VSWR of
less than 1.6:1.

Quality Construction

Double-ridged waveguide antennas are constructed of light-
weight corrosion-resistant aluminum and fiberglass, providing
years of trouble-free indoor and outdoor service. To maximize
performance, Type N connectors are used on Models 3115 and
3106, and Type K connectors are used on Model 3116.

Choosing Your Model: Three Models
with Frequency Ranges of 200 MHz to 40 GHz

200 MHz to 2 GHz

The Model 3106 has high gain and excellent VSWR character-
istics over its entire frequency range. It is especially effective
for generating high electromagnetic fields with relatively low
power input. The antenna is also useful for receiving low-level
signals where high gain characteristics are needed. Although
large in size, 93.3 cm (36.7 in), this antenna weighs only
11.8 kg (26 lb). A Type N female connector is used for
increased power handling.

1 to 18 GHz

The Model 3115 has excellent gain and VSWR characteristics.
This antenna is small and portable with a length of 24.4 cm
(9.6 in). The feed system uses a Precision Type N female
connector so the antenna can handle considerable power with
low losses above 12 GHz.

18 to 40 GHz

The Model 3116 is an extremely small antenna, offering
portability and increased efficiency. The Model 3116 has a
length of only 13.0 cm (5.25 in), and weighs just 135 g
(4.74 oz). A Type K female connector is used for increased
performance at high frequencies.
