INTRODUCTION 

 

The ETS-Lindgren  EMCO brand Model 3116 Double-

Ridged Waveguide Horn Antenna is a linearly polarized 

broadband antenna covering the frequency range of 18 GHz 

up to 40 GHz. The Model 3116 was designed and built 

specifically for emissions and susceptibility testing. 

 

The antenna is precision machined from aluminum. A 50 

V

 

type K female connector is mounted on the base block of 

the antenna for increased performance at high frequencies. 

 

Although the type K connector mates with type SMA 

connectors when used with SMA connectors the high 

frequency performance will be limited to the rating of the 

SMA connector. It is recommended that cables with type K 

connectors be used to ensure optimal performance.
