I am preparing a bill of materials for an AP install. The AP model is the cisco AIR-CAP2802E-B-K9. The antennas is AIR-ANT2524DW-R which is a dual band dipole. I noticed the 2802E has 4 antenna ports. Do we install an antenna on all 4 ports? So if we are purchasing 10x 2802s, we would need to purchase 40x antennas?
