I'd like to know if two endpoints in an RF communication system can have different types of antennas, like one directional (yagi) and the other omnidirectional (dipole).
I want to do this because I have an object that I'd like to have RF communication with. I don't know the exact orientation that this object will be in, but I would know its location relative to where I'd be communicating with it (ground station). Is it a good idea to use an omnidirectional antenna for the object, so that it can send/receive signals from all directions, and for the ground station to have a directional antenna pointed at the object? Would this work better than having two omnidirectional antennas at both ends?
Also, just in case this is relevant, the pair of RF modules communicating with each other are gonna be 900MHz Xbee XBP9B-DMST-002.
