Coaxial surge protection
An antenna in an open space or on a rooftop is susceptible to direct lightning strikes or induced surges from nearby strikes. Phoenix Contact’s coaxial surge protectors with low network performance loss protect wireless equipment from these dangers and safeguard equipment by redirecting the surge current to ground.
Types of surge protection technology include:
DC Pass protection is used on any application that used a multiplexer DC sign on the center conductor of the cable. DC pass applications include multiplexer bias-tees, amplifiers located at the top of the antenna tower, and low noise amplifiers (LNAs) such as those used on GPS antennas.
Quarter-wave technology
Quarter-wave coaxial surge protection technology is tuned for a frequency range that blocks DC. These protectors are typically used on wireless equipment such as wireless I/O, wireless Ethernet, HF, VHF, and UHF radios. They are also used on GSM, CDMA, UMTS mobile communications equipment.
