Towers, poles and support structures elevate, support and/or position personnel and equipment such as antennas, lighting, surveillance cameras or sensors, wind turbines, weather instruments, and power lines

Horn antennas are used for the transmission and reception of microwave signals.

Chip antennas are semiconductor ICs used to collect or radiate electromagnetic waves

Audio amplifiers and preamplifiers are units that amplify a sound signal, which is then sent to a speaker or another amplifier

Wireless systems consist of combined RF components such as transmitters, receivers, transceivers, filters, down / up converters, antennas and antenna positioners

Radio frequency identification (RFID) products read or write data to RF tags that are present in a radio frequency field projected from RF reading/writing equipment.
