NetPoint NPTR-1 Marine-Environment Parabolic Antenna
The NetPoint NPTR-1, manufacturer model NPTR1 / NPTR5-DP-2FT, is a directional parabolic antenna designed for point-to-point backhaul in coastal, high-salinity and demanding outdoor environments.
Its 2 ft reflector supports 4.9–6.4 GHz operation with gain up to 30 dBi. Dual polarization and two N-female RF connections support compatible connectorized radios. A separate radio is required.
Key Features
- 4.9–6.4 GHz frequency coverage.
- Up to 30 dBi antenna gain.
- Dual polarization with 45° slant or 90° configuration.
- Two N-female RF connectors.
- Integrated radome.
- Galvanized materials for demanding environments.
- Mounting hardware and N-to-RP-SMA pigtails included.
Directional RF Performance
The narrow radiation pattern concentrates energy toward the remote site. Accurate alignment, matching polarization and a clear radio path are essential when designing the link.
Marine-Environment Construction
The NPTR series combines corrosion-resistant construction with a protective radome for exposed installations. Seal external RF connections appropriately to prevent moisture entry.
Installation and Link Planning
Use the adjustable mount to aim the reflector toward the remote antenna. Calculate the link budget using the selected frequency, radio output, antenna gain and cable losses. Configure transmit power to comply with local EIRP limits.
Ideal Applications
- Coastal and port connectivity.
- WISP point-to-point backhaul.
- Remote industrial monitoring links.
- Wireless connections serving tropical or humid locations.
Compatible Products
Select a connectorized dual-chain radio operating within the antenna's frequency range. Use correctly mating RF jumpers, connect both polarization paths and configure the antenna polarization for the radio system.
- Ubiquiti AF-5XHD airFiber 5XHD Radio –. The radio has two RP-SMA RF connections. Operate within the shared, locally authorized frequency range and use the 45° slant configuration.
Important: This recommendation concerns RF use with the antenna. Connect the antenna feedlines to the radio's CH0 and CH1 RF ports, not its separate GPS connector. Radio power, Ethernet cabling and surge protection must be selected independently.
The AF-5XHD's published worldwide radio range is 4.8–6.2 GHz, subject to regional restrictions. It cannot use the antenna's entire 4.9–6.4 GHz range.
