Frequently asked questions
What frequency range do NPTR3 antennas cover?
NPTR3 antennas operate in the extended 5.9–7.2 GHz range, improving spectrum use in highly congested areas.
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?
Yes. NPTR3 antennas are designed for PtP links up to 100 km, especially with high-sensitivity radios and efficient modulation.
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.
