ETS-Lindgren 3152 Dual Array of LPDA Antenna 200 MHz - 1 GHz

The ETS-Lindgren Model 3152 is a dual array of LPDA antennas based on the successful ETS-Lindgren Model 3148B with a 200 MHz to 1000 MHz frequency range. The array arrangement provides an additional gain improvement of 3dB across the range, and a convenient space-saving design with the use of top hat-loaded, low-frequency elements.

Air Polarization
Both the 3151 and 3152 feature a convenient air polarization capability that reduces test time. Polarization occurs in a 90 degree arc at the rate of approximately 30 degrees per second. A customer supplied external source of compressed air at 410 - 550 kPa (4.1 bar - 5.5 bar or 60 psi - 80 psi) is required.
