KHOW operates with 5,000 watts and a directional antenna. A simple form of directional antenna is the loop aerial. The station has a highly directional antenna system. Most transmissions consisted of the 600 line pictures, which were telemetered by a directional antenna. Most transmissions consisted of 600 line pictures, which were telemetered by a directional antenna. The 600-line pictures were transmitted over a directional antenna. It uses a directional antenna at night. The hub is significantly wider, and comes with a detachable directional antenna. It is not a clear-channel station because of its frequency and highly directional antenna. The system requires a carefully aimed directional antenna. Ruckus designed an adaptive directional antenna technology called BeamFlex. Longer ranges utilise a directional antenna and geostationary satellites. The antenna on the detector car was a rotatable, highly directional antenna. In 2016 they commissioned Kintronic Labs to build a four-mast, parallel-array directional antenna system. The power was increased to 5,000 watts, with a directional antenna used at night.
