If you did two I'd put them together or if you space them make sure you don't space them a half wavelength apart so as to avoid have a section between the beads that would be resonant. The reason for spacing them might be to keep the RF away from the other equipment so you don't have the shielded ethernet cable re-radiating the energy in the equipment shack where it could take another place into the equipment.
