This document presents the electromagnetic compatibility test report for Sepura Limited's SC2024 radio antenna patterns. The tests were conducted by dB Technology (Cambridge) Ltd at their Radio Test Site. The report details the methodology used to establish the radiation patterns, including the equipment setup and the process of converting raw receiver readings to equivalent antenna gain measurements.
The report includes results for five different antenna models (300-00366, 300-00499, 300-00662, 300-01031, and 300-01032) at various frequencies ranging from 406 MHz to 470 MHz. Polar plots are provided for each antenna model and frequency, along with maximum, minimum, and average antenna gain values. The test setup involved placing the UUT on a turntable in an open area test site and measuring the received signal strength at different angles. Correction factors were derived to account for site characteristics and equipment calibration.
The document also includes photographs of the test setup, showcasing the equipment used and the positioning of the antennas during the measurements. This report provides valuable data for understanding the radiation characteristics of the tested antennas when used with the Sepura SC2024 radio.
