The ALC-100 is a broadband, linearly polarised Log Periodic Dipole Array (LPDA) Antenna, operating over the frequency range of 200 MHz to 1 GHz; and with excellent efficiency between 300 MHz and 1 GHz. This antenna is a compact version of the AL100, in that the overall length of the antenna has been reduced by over 13 inches, with only a slight compromise in overall performance.

Construction

The construction of the ALC-100 is identical to that of the AL-100 Log Periodic, in that it has been designed to be extremely durable, making it an ideal choice for daily use in laboratory environments, both indoors and outdoors, and even under continuous exposure to extreme weather conditions. The antenna elements are solid stainless steel, and the “feeder tubes” are constructed from the same heavy gauge, corrosion resistant aluminium.

Application

The ALC-100 Compact Log Periodic Antenna is intended for use as an EMI test antenna for qualification-level regulatory compliance measurements (FCC, CE, RTCA DO-160, FDA, SAE Automotive, etc.).

The ALC-100 can also be used in conjunction with an RF power amplifier (up to 50 watts) to generate RF fields associated with RF immunity tests. For high power applications, Com-Power’s ALP-100 Power Log Periodic Antenna is an excellent choice. In addition, a pair of ALC-100 Compact Log Periodic Antennas can be used in lieu of dipole antennas for Normalised Site Attenuation (NSA) calibrations of Open Area Test Sites (OATS) or Semi-Anechoic Chambers (SAC); thereby avoiding the time consuming process of tuning the dipole element lengths at each discrete frequency.

Notwithstanding the above applications, the ALC100 can also be used for site comparisons, shielding effectiveness tests of enclosures, field monitoring, site surveys and other general purposes.
