In principle, there are such antennas. However, the last Archer MR400 I ordered from Digitec no longer has RP-SMA antenna connections, but the antennas shown are fixed to the housing. I'm sure there is a way to convert it, but the device has to be opened and will probably lose its warranty. It is a pity, but now I have to look for an alternative product, as I have made many installations with the predecessor model Archer MR200 with external antennas.
