By using simple cascading (looping), the TG 1000 system can operate up to 24 channels (12 devices) without external antenna splitters. For this, use the "WA-CKL" cable set, which is available as an optional extra. Connect the antennas to the first receiver and then connect a maximum of 11 additional receivers using the "WA-CKL". All receivers are then supplied with the RF signal via the first receiver.
