The WTR-20 pairs a W-2 transmitter with a W-2 receiver for supported Antari machines, giving manual wireless control without a cable to run.
Antari lists it as compatible with the AF-4R, MB-20, S-500, S-500L, Z-390 and M-11, so one kit type covers a mix of fog and snow machines. Optional radio frequencies are 315 and 433 MHz. The transmitter is small at 57 x 28 x 10 mm.
