Point-To-Point (PTP) Lightning Protection Unit

Cambium Point-to-Point (PTP) 250, 300, 500 and 600 Series Solutions include robust radios designed to withstand the toughest conditions. Because they are often perched on high towers, sometimes with antennas, they are located in situations that can attract lightning. The Cambium PTP Lightning Protection Unit (PTP-LPU) is a device that shields your PTP radios from the harmful effects of sudden surges in power induced by electro-magnetic activity (lightning). While you can purchase a Cambium All Risks Extended Warranty that covers lightning strikes, the warranty only covers the cost of replacing the radio. It is a good idea to start out with lightning protection at initial deployment to avoid the delays and costs associated with taking down damaged devices and installing replacement units.


The PTP Lightning Protection Unit offers two protection methods – line-to-line and line-to-ground – to ensure that a surge in power is stopped in its tracks. When installed correctly, using solid shielded CAT5e cable, the will ground the surge almost instantaneously (typically within five nanoseconds). By grounding the power surges before they can harm the units, the Cambium PTP-LPU gives your radios the best possible protection from the harmful effects of lightning. However, 100% protection is neither implied nor possible.

PTP-LPU units have a projected operational life of 10 years. The device's metal enclosure provides a tough body armor that protects your units against battering from winds up to 150 mph (242 kph), rain, ice and snow.
