SE77 Series High Gain YAGI Antenna System

In order to ensure ease of mobility of the antenna system, it is configured to be stored in package less than thirty-six (36”) inches long and approximately thirteen and one half (13 1/2”) inches in cross-section.

The C122 antenna consists of two yagi arrays which are located 90 degrees from each other and share the same center axis. Each array consists of five dipoles which have the proper length and spacing ratio required of an efficient yagi array. The C122-3 Series antenna adds three (3) additional dipole sets for increased gain with a minimum weight increase. This element extension is also available as an option under the part number U113-1.

The C122 antenna series provides the extra margin of antenna gain required for secure transmissions.
