Broadcast Field Measurement Products
5/27/2020
For broadcast stations, field strength measurements must be made at known locations around the antenna system. These measurements should be made on a regular interval with a calibrated antenna. Measurements must be made of the station’s fundamental frequency as well as the side lobes and harmonics to meet the spectrum mask required by the regulatory body.

Horn Antennas
Broadband antennas, compared to half wave dipoles, reduce test time because the technician did not have to stop the test to adjust the dipole antenna for each frequency. Most compliance standards now require the use of such antennas. The latest version of Mil-Std 461E states the used of broadband double ridge guide horn antenna as the antenna of choice for frequencies above 200 MHz.
