Hola, es posible utilizar esa antena (https://ashgps.com/2/Antenna%20Specifications/ASH111661/ASH111661.pdf) pregunto más que nada por que no estoy seguro que el simpleRTK2B pueda alimentar la antena.
Caso contrario, qué alternativas tengo para usar dicha antena en la Base?
Most Ashtech receivers output 4.5-5V
To use this type of antenna you’d need a powered splitter or a bias-tee, with a DC block/resistance on the ZED-F9P side, and power injection on the antenna side.
Clive, nice to see you here too! (I know you from STM32 and from ublox forum!)
Ok, I will try to find a powered splitter.
Brands I run into most are “GPS Source” and “GPS Networking”, often find on eBay, but not sure of the international availability. Would avoid HP GPS splitters, as these frequently block everything other than GPS L1
On the maker side you might find satellite TV coax splitters that offer DC blocking and powering.
ublox antenna is labeled as Active Antenna, I’m wondering if AS is providing power supply to ublox antenna and if it could work with ashtech. Is there a schematic for AS?
They are supplying 3.3V, with a circuit equivalent to that in the Hardware Integration Manual.
I don’t believe it is a sufficient voltage for the specified Ashtech/AeroAntenna
it could be nice to have an external pin to power antennas….
