Our take on the L1/L2/L5 High Performance Multiband RTK GNSS Active Quad Helix Antenna White

This is an active quad helix GNSS antenna covering GPS L1/L2/L5, GLONASS G1/G2/G3, Galileo E1/E5a/E5b, BeiDou B1I/B2I/B1C/B2a/B2b, SBAS L1/L5, QZSS L1/L2/L5 and IRNSS I5. The helical element gives tight pattern control and polarization purity in a compact housing, so it receives the L2 and L5 signals that L1-only antennas miss and supports RTK-level accuracy. It has an integrated SMA connector, an O-ring seal and IP67 automotive-grade construction, which suits retrofits and builds where integration effort should stay low. Compared with patch antennas it is smaller and more resistant to multipath, though it is a specialized component rather than a plug-and-play receiver.

Pros
  • Covers L1, L2 and L5 plus all major constellations
  • Quad helix element gives strong pattern control and polarization purity
  • Compact form factor with integrated SMA connector
  • IP67 automotive-grade housing with O-ring seal
  • Low integration effort for retrofits
Cons
  • Needs a receiver that supplies power and handles the multiband signals
  • No cable or mount included
  • Specialized part, not a standalone positioning device
  • Performance depends on ground plane and installation

About the L1/L2/L5 High Performance Multiband RTK GNSS Active Quad Helix Antenna White

This is an active, multi-frequency GNSS antenna for high-accuracy positioning. It receives GPS L1/L2/L5, GLONASS G1/G2/G3, Galileo E1/E5a/E5b, BeiDou B1I/B2I/B1C/B2a/B2b, SBAS L1/L5, QZSS L1/L2/L5 and IRNSS I5. It is made for applications that need more accuracy than an L1-only antenna can give, such as GIS and RTK.

The antenna uses a quadrifilar helix structure. This gives it good pattern control and polarization purity, and high efficiency in a small body. It is ground plane independent. The housing has an integrated SMA connector, an IP67 rating, automotive grade electronics and an O-ring.

It needs little integration effort and can be used to retrofit existing products.

Questions and answers

What is the difference between this and an L1-only antenna?
It receives L2 and L5 in addition to L1, plus GLONASS, BeiDou, Galileo, SBAS, QZSS and IRNSS bands. That extra signal set is what enables RTK-level accuracy and better resistance to multipath.
Does it work with any GNSS receiver?
It works with receivers that support multiband GNSS and provide bias power to an active antenna through the SMA connector. An L1-only receiver will not use the L2 and L5 signals.
Is it weatherproof?
Yes. The housing is IP67 automotive grade and includes an O-ring at the connector for a sealed mount.
What is in the box?
The antenna with its integrated SMA connector and O-ring. No cable, mount or receiver is included.
Can I use it for RTK?
Yes. It is designed for RTK and other high-accuracy work, provided the receiver and correction service support it.
Where is the L1/L2/L5 High Performance Multiband RTK GNSS Active Quad Helix Antenna White cheapest?
