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.
