DIY Drones part number:
Antenna 900MHz RP-SMA 2dBi
Antenna 433MHz RP-SMA 2dBi
I ordered two of each, I just received them today, and there's no label on the packages, and they look absolutely identical.
There is a blue dot on two of them, and there's not a blue dot on two of them.
Anybody know which is which?
Anybody know what would happen if you use the 900 antenna on a 433 mghz 3dr?
Hi Dan, the 433MHz antennas have a blue dot on them, 915MHz antennas do not.
I ordered two 3DR modules 433 Mhz with antennas from RCT and due to bad performance I changed this antennas to a 2.4 Ghz one.
In 3DR Config Tool I noticed no difference in RSSI and noise value.
So for further investigatin I made a X-Ray from both 433 Mhz antennas and the 2,4 Ghz one.
I was surprised, that I could not see any difference between this antennas.
Looking at the dimensins of all three antennas, they should be all lambda/4 Dipols for 2,4 Ghz.
Maybe anybody can comment this...
