The SPK6618H is the latest advancement in GNSS antenna technology allowing tri-band (L1/L2/L5) reception for GPS, GLONASS, Galileo, and BeiDou constellations. These 'UFO' antennas have incredible performance for the money. The antenna has a built in ground plane with significant filtering and amplification of both L1, L2, and L5 frequencies for all GPS, GLONASS, Galileo, and BeiDou satellites. Excellent for surveying or fixed antenna applications.
Designed for the latest u-blox F9 platform it provides a fast, easy, and reliable multi-band antenna solution but can be used with any GPS/GNSS receiver that can benefit from the L1/L2 dual or L1/L2/L5 triband reception. While this antenna works great with normal L1 GPS/GNSS receivers it will not make your $20 receiver into a $200 receiver. Please check your receiver to verify it is capable of using the L1 and L2 signals that this antenna outputs. If your receiver is not compatible with L5, that is ok too, there is no harm using this tri-band antenna.
We disassembled a unit because we love to see how things work! The antenna incorporates a 130mm ground plane with six hybrid couplers to obtain signal phasing which makes this design a lot more insensitive to manufacturing-imposed issues (e.g. board material with inconsistent dielectric).
It is important that you are also aware of the unique connection points on this antenna as the data and mounting connectors may be new to some users. This antenna has a TNC female connector found on nearly all surveying antennas. We recommend a TNC Male to SMA adapter or cable when using with our GNSS receivers. Also, this antenna uses a standard 5/8"-11TPI (threads per inch) connector found on surveying equipment. This is not compatible with a camera tripod. We recommend a 5/8" to 1/4" tripod adapter. You can also find 5/8"-11TPI threaded rod in most hardware stores in North America. For information about permanently fixing this antenna to a roof, please see our tutorial on How to Build a DIY GNSS Reference Station.
Note: An RTK Express, tripod, and all other accessories are not included with the GNSS Multi-Band L1/L2/L5 Surveying Antenna. These parts will need to be purchased separately.
Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
