EMCO (ETS-Lindgren) 3115 Double-Ridged Waveguide Horn Antenna 750MHz - 18 GHz

Power Input

This horn antenna uses a Type N precision connector and accepts up to 300 watts of continuous input power. The antenna's high gain and low VSWR over its operating frequency translates into efficient amplifier use and higher field strengths.

Construction

An antenna constructed to maximize structural integrity is better able to maintain its electrical properties. The benefits are better measurement repeatability, lower uncertainty values and longer calibration validity. Constructed of powder coated aluminum plate, the 3115 will provide years of trouble-free indoor and outdoor service. This antenna is small and portable with a length of 24.4 cm (9.6 in). This antenna includes a 1/4 in x 20 tripod mount.​ 

Mounting Instructions

The following instructions allow the user to mount the Model 3115 on an ETS-Lindgren or compatible tripod.

Step 1. For packing purposes, the Model 3115 is shipped with the mounting bracket attached in reverse. Before the antenna may be mounted on a tripod, the user must remove the wing nut and separate the antenna from the mounting bracket.

Step 2. To mount the antenna on a tripod, attach the mounting bracket to the tripod with the ¼-20 bolt provided. Next, attach the antenna to the mounting bracket by fitting the position lock (small posts on the mounting plate) into the indentation provided on the mounting bracket, then tightening the wing nut. To rotate the antenna, loosen the wing nut, reset the antenna in the desired position lock and tighten the wing nuts.

Step 3. After the Model 3115 antenna is mounted onto the tripod or tower, connect a type N coaxial cable from the female antenna connector to a signal generator or amplifier.
