Bias Tee

Andrew Solutions bias tees are designed to protect equipment from damaging transients induced by lightning strikes. This product allows the injection of dc current to the center conductor of the feeder line, allowing current to travel to the top of the tower. Bias tees are unidirectional devices. Ports are clearly marked to show mounting direction with either “Antenna” or “Radio”.

dc Block

The dc block is designed to block dc signals from passing through the center conductor of a coaxial transmission line. The dc block is a bidirectional RF device. Either RF port may be connected to the equipment side or the antenna side of the transmission line interface to provide equivalent protection.

Replaceable Gas Tube Surge Arrestors

Offering broadband performance from 0–2200 MHz and excellent electrical characteristics, Arrestor Plus® replaceable gas tube surge arrestors are easy to install, are bidirectional, and feature dc pass capability through the center conductor to the active tower top electronics. The unit’s removable cap makes periodic maintenance fast and easy.

Integrated Surge Arrestor/Connector

The Arrestor Plus® integrated, T-series lightning surge arrestor is a onepiece surge arrestor/HELIAX® connector. It uniquely combines the reliability of quarterwave shorting stub technology with the proven performance of HELIAX connectors to deliver premium lightning protection in a single component.

Arrestor Plus® T-Series Surge Arrestors

Arrestor Plus T-series surge arrestors give engineers more flexibility when configuring lightning protection systems. This slim profile arrestor fits easily inside equipment enclosures, is bidirectional, and offers true multistrike protection. The arrestor plus bulkhead mount T-series features universal Type N and 7-16 DIN interfaces. The dc passing version allows current to travel to the top of the tower.
