Frequently asked questions
What frequency range do NPTR3 antennas cover?
NPTR3 antennas operate across 4.9–6.4 GHz (licensed and unlicensed), covering 5 and 6 GHz with one reflector.
What gain do NPTR3 antennas offer?
Per the NPTR3 datasheet, gain is Low 35 / Mid 36 / High 37 dBi.
What connector do NPTR3 antennas use?
They use low-loss N-female connectors and ship with N–SMA jumpers compatible with Mimosa, Cambium, and Ubiquiti radios.
Are they suitable for long-distance links?
Per the NPTR5 product page, reference PtP range is 100 km (62 mi).
What is the typical VSWR?
Per datasheet, VSWR HPOL stays < 2.0.
What polarization do they support?
NPTR3 antennas use dual-slant ±45° polarization, ideal for MIMO 2×2 efficiency in backhaul environments.
What materials are used? Are they weatherproof?
Yes. They use treated aluminum with anti-corrosion coating and a fiberglass radome resistant to UV and rain.
Can they be used with 6 GHz Wi‑Fi 6E or licensed LTE radios?
Yes. They work with radios in the upper 6 GHz band, including Wi‑Fi 6E backhaul, LTE-LAA, and custom solutions.
What is the recommended minimum link distance?
They can work on short hops, but a minimum of about 3 km is recommended to avoid overpower and protect the Fresnel zone.
Is a special tower or mast required?
Mount NPTR3 antennas on 2-inch steel masts or towers at least 6 m high, with precise aiming and firm anchoring.
What accessories can I use?
You can add NetPoint RF shields, wind-load radomes where needed, and the SANP stabilizer arm for more professional installs.
What makes the NPTR series different from other parabolic antennas?
NPTR is designed specifically for aggressive environments (coastal climates, high salinity, and extreme humidity). Unlike standard antennas, NPTR hardware uses hot-dip galvanizing and stainless fasteners to avoid premature corrosion.
Is extra connector protection required?
Yes. Even though the antenna is rugged, sealing connections with self-amalgamating (vulcanizing) tape is essential to keep moisture out of the jumpers and protect the link.
What is the estimated service life?
Estimated service life in extreme environments is 12 years, subject to a technical assessment of the installation site.
Which industries use NPTR?
Mining, energy / oil & gas, and marine applications — plus ports, wind/solar parks, coastal surveillance, rural connectivity, and beach resorts.
