Choosing a High-Precision GNSS Antenna: Bands, Gain, Phase Centre and Mounting
The antenna sets the ceiling on a receiver's observation quality, so start with bands. Single-frequency is enough for standalone positioning; RTK fixed solutions, multi-constellation solving and multipath-heavy sites call for a multi-band antenna covering GPS L1/L2/L5, GLONASS and BeiDou. The YUEETEK SK6640 high-precision antenna system covers these bands with a built-in LNA.
For RTK base stations and all-band GNSS integration, review the GNSS industry applications and the ODM/OEM custom development process, then confirm connector, cable, mounting and environmental requirements with YUEETEK. The antenna can be evaluated alongside the customizable RTK GNSS module when the receiver and antenna are specified as one system.
Two specifications matter most: peak gain and phase-centre stability. Peak gain of at least 5.5dBi maintains carrier-to-noise ratio in weak-signal environments, while a phase-centre deviation under 2mm drives survey repeatability; VSWR, axial ratio and IP67 protection complete the picture. The full method is covered in our high-precision GNSS antenna selection guide.
For specifications, download the high-precision antenna systems datasheet (PDF); for complete systems compare the handheld GNSS RTK receiver and the customizable RTK module PCBA, or review the Product Selection Guide. Connectors, cabling and mounting are confirmed per project — contact us for pricing.
Ground plane and mounting position: A high-precision antenna needs a stable metal ground plane to preserve gain, axial ratio and phase-centre consistency. Reference stations and fixed base stations should use a sufficiently large ground plane or choke ring, with the phase centre clear of nearby metalwork; integrated terminals should reserve a keep-out zone below the antenna so batteries, shields and connectors do not enter the near field. Keep the antenna away from transmitters and strong reflectors, mount it as vertically as possible, and reduce multipath effects on C/N0 and RTK fixed solutions.
Mounting and cable loss: Survey-grade antennas are commonly mounted on a tripod, range pole or fixed mast. Confirm connector torque, waterproofing and lightning/earth bonding; vehicle and equipment installations must account for vibration, wind load and cable strain. Longer cable runs increase loss, and the difference between GPS L1 and L2/L5 attenuation can affect dual-band solving. Use low-loss coaxial cable, minimise adapters, and verify voltage and current headroom at the active-antenna power injector.
Acceptance checks: After installation, review C/N0 and visible-satellite count per band, then compare repeated measurements on a known point. Where multipath is obvious, re-test after changing the mounting position, enlarging the ground plane or adjusting antenna height. For project-specific connectors, cables, mounting adapters or outdoor protection, see our outdoor positioning guidance or contact us.

PRODUCT FAQ
High-Precision Antenna Systems FAQ
How do I choose the right receiver or module?
Start with the working scenario, accuracy requirement, communication method and installation conditions, and we will suggest a model and a configuration list. The three product lines serve different purposes: choose the handheld receiver when you need a complete device, the customizable RTK module PCBA when you integrate positioning into your own terminal, and the high-precision antenna system when you need reliable satellite signal reception. See the selection guide for a side-by-side comparison.
Which accuracy figures are published?
The published figures are: the handheld receiver supports multi-constellation, multi-frequency joint solving with RTK fixed solutions, and the high-precision antenna system has a phase center error of <±2mm. The positioning accuracy of the customizable RTK module PCBA, as well as the communication interfaces, battery life, dimensions and weight of the handheld receiver, are not published as fixed numbers and depend on the project configuration - please confirm with sales.
Do you support ODM / OEM customization?
Yes. Customizable dimensions include frequency bands, interfaces, form factor, firmware and certification requirements; the exact scope and minimum order quantity are assessed per project.
Which satellite frequency bands does the antenna system cover?
The frequency range covers GPS L1/L2/L5/L-band, GLONASS G1/G2 and BeiDou B1/B2/B3. The antenna uses RHCP polarization with 360-degree horizontal coverage, 50 ohm impedance and 40±2dB LNA gain.
What are the operating temperature and protection rating of the antenna system?
The operating temperature range is -45 to +70 degrees Celsius and the protection rating is IP67. Mechanical dimensions are D150 x H58.4mm, the connector is TNC-K and the weight is 450g or less.
