I am interested in Reach Rtk and would like to know if it is possible to get precise positions with Reach Rtk using Trimble Zephyr 2 Antenna on a pole?
If other antennas can be used – does Reach Rtk get more precise positions with other (expensive) antennas?
According to the datasheet of Trimble Zephyr 2 antenna its input voltage range is from 3.5V to 20V.
Reach provides antenna with 3.3V, so officially they are not compatible.
There’s a chance that 3.3V would be enough for this antenna, but no guarantees.
Also, you can use a cable with a power injector to provide required voltage to the antenna.
Big survey grade antennas usually provide better performance, but are less suitable for integration because of the size and weight.
These antennas have wide voltage input range: 2.5 to 16 VDC. Reach supplies 3.3V, so they are compatible. Connector option will depend on where you purchase the antenna, you can even order it with custom connector/cable from Tallysman (MOQ might apply). For Reach you will need MCX connector, but adapters exist that will allow you to make connection without need to solder anything.
Well, price here is not an issue, another question arises, what keeps us from using other frequencies from the satillites? L2C, L5, and L1C? It looks like RTKLIB does support these.
