Com-Power ALP-100

Com-Power ALP-100 High Power Log Periodic Antenna is lightweight, compact, rugged. It has low VSWR and high power handling capabilities. So it can be utilized as a receiving antenna for radiated emissions tests, or as a transmitting antenna for radiated immunity tests. It is suitable for use in any normal test environment, such as an absorber-lined chamber or outdoors on an open area test site. It operates over the frequency range of 200 MHz to 1 GHz.

The Log Periodic antennas are used for emission and immunity testing to verify compliance for FCC, CE and MIL-STD 461 specifications. Log Periodic antennas allow quick sweep measurements without a band break. This feature makes it convenient to use the Log Periodic antenna with a automated emissions or immunity measurement system. The size of the antenna also allows it to be used in a small area like a shield room. The Log Periodic antenna was designed to get a smooth response curve for the antenna factors to minimize measurement errors. The calibration data provided with each antenna is used to calculate field strength measured for the selected frequency. The antenna factor (dB/m) for the selected frequency is added to the measured output (dBV) displayed by the EMI meter to obtain field strength (dBV/m).
