The TOP106 from TOPGNSS is a GNSS/GPS antenna capable of receiving the L1/L2 bands 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 and L2 frequencies for all GPS, GLONASS, and BeiDou satellites. Excellent for surveying or fixed antenna applications. If you can handle the extra weight and size in your application, the TOP106 is the best antenna we've played with to date.
The TOP106 without RF shield is ideal for handheld surveying or portable applications. It is smaller and lighter weight than the BT-147 weighing in at 422g. For automobile applications please see our u-blox ANN-MB-00 GNSS antenna. For weight sensitive applications (like RTK Drones) checkout the BT-560 helical GNSS antenna.
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 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.
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).
Note: This antenna has a TNC female connector found on nearly all surveying antennas. We recommend our TNC Male to SMA cable when used with our GNSS receivers.
Note: 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.

Fully recommended. An excellent antenna. Good value for money. It captures the signal of all the satellites available in the area. Currently I use it with an Emlid Reach M2 and I can compare its performance with other gnss that I have at work and this little antenna is capable of receiving the same amount of satellites as expensive antennas and expensive devices.
I've been unable to get an official survey of my property.
I've used this to get an unofficial survey of the water boundary, building area and electrical line and well site for my future home.
This gives me detailed information for my planning documents for permits, since there's offsets from all the locations required for septic systems in the area.
I just wish I could by two. Then I could do a pretty official property boundary based on the section corner in the neighboring lot.
