The Cambium PTP 650/670 LPU and Grounding Kit is part of the PTP 650 Wireless Broadband solutions which are ruggedized to operate in the toughest environments. Lightning strikes are the most typical cause of system outages or failures of mast-mounted equipment, especially when mounted as high as 300m. Therefore, lightning protection is critical to minimize the potential for damage. Cambium Networks strongly recommends that all PTP 650 installations should be deployed with the PTP-LPU. Network operators should always follow best-practices for grounding and lightning protection. Doing so will minimize network outages and reduce the associated costs of tower climbs and equipment repair/replacement.
