"dummy load", specifically "50 ohm dummy load", because that's the standard impedance of most antennae. (Oddly enough, the TV antenna is engineered for a 75-ohm impedance, but that's beside the point.) However, even dummy loads radiate a little bit. It's common to test handheld radios a few feet from each other with dummy loads screwed onto the antenna ports, because when you've got 115dB of link margin and your dummy loads are only eating 50dB on each end, that's still plenty!
