PRODUCT SPECIFICATIONS
NetPoint NPTR-2 3-Foot Dual-Polarized Parabolic Antenna
The NetPoint NPTR-2, identified by the manufacturer as NPTR2 / NPTR5-DP-3FT, is a directional parabolic antenna for point-to-point wireless backhaul. It operates across 4.9–6.4 GHz and is marketed in the 34 dBi gain class.
Designed for demanding coastal and high-salinity environments, the antenna combines galvanized materials with a protective radome. Its dual-polarized feed provides two RF connections for suitable external radios.
Key Features
- 4.9–6.4 GHz operating range.
- 3-foot nominal antenna size.
- Manufacturer-listed gain values of 32.5, 33.5 and 34.5 dBi across the band.
- Dual-slant polarization.
- Two N-female RF connectors.
- Radome, mounting hardware and N-to-RP-SMA pigtails included.
Directional RF Performance
The manufacturer specifies a 3.84° beamwidth in both polarization planes. This narrow radiation pattern suits focused backhaul links and requires careful alignment. Link performance depends on the radio, channel, interference, cable losses and propagation conditions.
Outdoor and Coastal Design
The NPTR series is intended for harsh environments where corrosion resistance matters. The included radome protects the antenna assembly, while the adjustable mount assists alignment during installation.
RF Connectivity
Dual N-female ports connect the antenna to an external radio through suitable coaxial jumpers. The antenna is passive: radio electronics, Ethernet connectivity and power delivery belong to the separately selected radio system.
Ideal Applications
- WISP point-to-point backhaul.
- Coastal and port connectivity projects.
- Industrial wireless links in high-salinity environments.
- Directional links between buildings or remote sites.
Compatible Products
Select a two-chain radio whose operating channels fall within 4.9–6.4 GHz. Connect both antenna ports using suitable RF jumpers, and match polarization at the opposite end of the link.
- MikroTik NetMetal 5 RB922UAGS-5HPacD-NM-US – its two RP-SMA female antenna connectors support connection through correctly terminated N-male-to-RP-SMA-male jumpers.
Important: The antenna does not extend a radio's supported frequency range or make different radio protocols interoperable. The NetMetal 5 requires its own specified power source; power is not supplied through the antenna's RF connectors.
