The EM-6899 passive vertical 41 inch rod antenna intended for receiving or transmitting applications in the 1 kHz to 50 MHz frequency range. Typical applications include measurements of shielding effectiveness to MIL-STD-285 and NSA 65-6 and radiated immunity testing. A band switch optimizes the antenna’s performance for two frequency ranges and it may be used with amplifiers as large as 300 watts continuous output power.
