Amplifier Research ATR26M1G Log Periodic Antenna 26 MHz – 1 GHz

Description

Amplifier Research ATR26M1G is a wide band, high gain, log periodic 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 combined with additional innovations, provides a size reduction of approximately 75% without sacrificing key electrical performance such as gain and beamwidth.

The ATR26M1G features a reduced profile and extremely low VSWR making it an excellent choice for high field-strength immunity testing. The considerable size reduction minimizes field loss resulting from room loading. This is especially troublesome when conventional log periodics are used in moderate-size enclosures. The exceptionally broad frequency range addresses existing RF susceptibility requirements as well as anticipated future developments and is matched to work directly with ARs W and A series RF power amplifiers. The robust design can accommodate the high power levels necessary to generate significant E-fields.

The ATR26M1G can also be calibrated for RF emissions testing. This antenna is built tough enough for outdoor use. The antenna comes with a wall bracket but can also be mounted in two perpendicular planes with the AP5010B antenna positioner.

The Model ATR26M1G antenna allows polarization change without removing the antenna from its positioner
