Horn Antenna

Features

Broadband - For sweep measurements

High Gain - Lower Floor Noise for Emissions

Two year warranty

Individual calibration

Application

This antenna is suitable for ANSI 63.4, CISPR16, EN

55022, FAA and other EMC standards that require

emissions and immunity testing.

The high gain reduces input power requirements to

generate high electromagnetic ﬁ eld levels for immunity

testing. High gain also increases antenna sensitivity

to low level signals.

During emissions measurement, the ﬁ eld strength

(dBV/m) is calculated by adding the antenna factor

(dB/m) to the voltage measured (dBV) at the antenna

terminals.

For immunity testing, the input power requirement P

in Watts to generate E Electric Field Strength in V/m

at a distance in D meters can be calculated by using

the following formula:

P = E

x D

/ 30 x Numeric Gain

G = 20 log F -29.79- AF

G = 10 log (Numeric Gain)

Where

G= gain in dBi

F = Frequency in MHz

AF = antenna factor in dB

AH-118

Description

The Horn antenna Model AH-118 is a standard

broadband double ridged waveguide horn antenna.

This antenna is linearly polorized and is designed

speciﬁ cally for EMC measurements for the 1-18 GHz

frequency range.

The AH-118 Horn antenna can be used for emissions

and immunity testing. The gain of this Horn antenna is

at least 6.1 dBi over the entire frequency range. Model

AH-118 can accept up to 300 Watts input power in

continuous mode.

This antenna is constructed using light weight alumi-

num with a corrosion resistant conductive coating.

The mounting base of Model AH-118 has 1/4 inch x

20 threads. This allows the antenna to be mounted on

a tripod (Model AT-100) or a tripod with matching

threads.

Each antenna is individually calibrated at 3 meters.

The calibration data and certiﬁ cate will be shipped

with each antenna.
