Network antenna Cambium Networks PTP 820S, radio 24–38 GHz, 48 V DC, IP66, 10/100/1000Base-T

The Cambium Networks PTP 820S is a point-to-point microwave radio unit for outdoor wireless backhaul operating in the 24–38 GHz frequency range. Designed for licensed microwave links, the unit provides Ethernet connectivity at 10/100/1000Base-T and supports standard networking protocols such as IEEE 802.1Q VLAN tagging, 802.1p QoS, 802.1ab LLDP and common Ethernet standards. The compact weather-resistant enclosure with IP66 rating and a DC power input makes the unit suitable for deployment on towers and rooftop sites where robust, high-capacity links are required.

Advantages

The PTP 820S combines microwave radio performance with integrated networking features to deliver a high-capacity, low-latency transport solution. Its support for Gigabit Ethernet and standard VLAN and QoS protocols enables seamless integration into service provider and enterprise networks. The IP66-rated housing and DC power operation simplify outdoor installation and reduce the need for specialized sheltering. Compact dimensions and a focused frequency band provide options for licensed point-to-point links with predictable interference characteristics.

How to use

Install the PTP 820S on a suitably rated pole, tower bracket or rooftop mount with a clear line-of-sight to the remote unit. Connect the Gigabit Ethernet port to the network using shielded Ethernet cabling and provide 48 V DC power via the recommended power inserter or DC feed. Configure basic network parameters—such as link IP addressing, VLANs, and QoS—using the device management interface or centralized network management system. Align the antenna for maximum received signal strength and verify link performance with the built-in monitoring and diagnostics.

Recommendations

Position units to ensure unobstructed line-of-sight and sufficient link margin for licensed operation; use professional alignment tools and follow local licensing rules. Use surge protection and grounding practices appropriate for outdoor microwave equipment and deploy shielded Ethernet cabling for any exposed network runs. Regularly monitor link statistics and perform periodic firmware updates as provided by the manufacturer to maintain performance and security.
