i saw someone posted geodetic antenna that can be use on reach m2 module, that particular antenna is Harxon GPS500. and someone from emlid said the following requirements on choosing antenna for M2 are
Antenna output current no more 100mA
Antenna DC bias no more than 3.3V
however, someone posted success on using Harxon GPS500 which has 3.3v to 12v DC.
Im new to this, and need your advice.
what is the difference Antenna DC bias and Operation Voltage?
sir, i have seen many antennas has thesame specifications with gps500, mostly made in china. like TOPGNSS and BEITAN, do you think i will work on my M2.?
Antenna DC bias is the interval of voltages that the antenna can operate with. Antenna Operation Voltage is the particular voltage used by this antenna during operation.
Reach M2 can supply up to 3.3V of voltage to the antenna, so according to these datasheets, both antenna should work fine.
