The CAM Calibrated Antenna is a directional horn antenna used for field intensity measurements and susceptibility tests, point-to-point communications and other RF / Microwave applications. It is linearly polarized, with high directivity and high front to back ratio. It is tripod mountable. It operates in the frequency range 4.19 to 7.74GHz, has a typical VSWR of 3:1, a midband gain of 25 dB, and a directivity of 10?.
