April 4, 201610 yr Could you suggest what I would need to connect a 30 foot cat6A cable running from a DVR downstairs to the loft space upstairs. I'm considering 4 channel baluns? passive or active I understand the active needs power are there any other reasons to pick one against the other. On my cat6a cable it reads LSZH-CO1-003-003-09-038 (2014/32) 146200
