Amplifier Research ATR26M6G Log Periodic Antenna 26 MHz – 6 GHz
Description
Amplifier Research ATR26M6G High Gain Log Periodic Antenna 26 MHz – 6 GHz is a wide band, radiant arrow antenna that is uniquely suited for use in both traditional applications as well as in new compact chambers.
The proprietary design utilizing a “bent element¨ approach provides a size reduction of approximately 60% without sacrificing key electrical performance such as gain and beamwidth. The considerable size reduction minimizes field loss resulting from “room loading”. This is especially troublesome when conventional log periodics are used in small enclosures.
The exceptionally broad frequency range addresses existing RF susceptibility requirements as well as anticipated future developments and is matched to work directly with AR’s “W” and “A” series RF power amplifiers. The robust design can accommodate the high-power levels necessary to generate significant E-fields.
The ATR26M6G can also be calibrated for RF emissions testing. This antenna is built tough enough for outdoor use. The Model ATR26M6G allows polarization change (90-degree rotation) without removing the antenna from its positioner.
