Sennheiser Passive directional antenna 1800 MHz

The Sennheiser AD 1800 is a passive directional antenna designed to improve wireless communication and reception for systems operating in the 1400–2400 MHz frequency range, including 1800 MHz microport applications. Featuring a BNC 50-ohm connection, approximately 4 dB gain, and a 100° beam angle, it is particularly useful in areas where standard telescopic antennas may not provide sufficient reception. Its compact design includes a mounting thread for use with stands or micro tripods.

The Sennheiser AD 1800 1G8 Passive Directional Antenna is designed to improve wireless signal reception in challenging environments where standard telescopic antennas may not provide adequate performance. Covering a broad 1400–2400 MHz frequency range, the antenna is suitable for wireless communication applications in the 1800 MHz band, including compatible Sennheiser microport systems.

As a passive directional antenna, the AD 1800 focuses reception toward the desired signal source, helping improve wireless communication reliability in problematic reception areas. It provides approximately 4 dB gain and a 100° beam angle, while its front-to-back ratio of greater than 14 dB helps provide directional characteristics and reduce reception from the rear.

The antenna uses a BNC connector with 50-ohm impedance for connection to compatible wireless equipment. For flexible installation, it features a 5/8" mounting thread with a reduction to 3/8", allowing it to be mounted on a stand or compatible micro tripod.

With dimensions of 180 x 192 x 22 mm and a weight of only 116 g, the AD 1800 is compact and lightweight enough for portable wireless setups while remaining suitable for professional installations.
