Antenna size alone shouldn't make them particularly hard to use in space. While there are forces acting on the antennas from the fields' interactions with deflected particles, it's not like trying to move a square mile array at high speed through a dense medium like the atmosphere (which of course is not a thing we do on earth - transmitters are static). Submarine receiving antennae are just great big long straight wires which would be even easier in space.
Mass will be a factor given their probable need to handle high current loads; packing and unfurling seems to be a thing we can do quite well; stabilizing them and keeping them in the correct orientation as the ship accelerates and the fields deflect particles could be really hard or quite easy, I have no idea.
