EMC Antennas
Model 3117
Double-Ridged
Waveguide Horn
for automated testing. It has the
widest usable frequency range of
any antenna in its class, with no
performance degradation from high
order modes.
Power Input
The Model 3117 uses a Type N
connector and accepts up to
300 watts of continuing input
power with up to 400 watts of peak
power. The antenna’s high gain
and low VSWR over its operating
frequency translates into efficient
amplifier use and high field
strengths.
Uniform Gain, Low VSWR
The Model 3117 has a more
uniform gain and antenna factor
because of the better behavior of
its radiation pattern. Since the
pattern is stable over frequency,
the gain and the AF also remain
stable. Similar antennas of this
class exhibit large variations of the
gain and the AF as the frequency
increases.
Flexible Mounting System
The Model 3117 antenna includes
both an EMCO classic mount and a
rear “stinger” mount.
