Airwavz RedZone Receiver can access any frequency 50 MHz to 1 GHz, and cover just beyond TV Channel 83.

All of Airwavz television receivers support 50 MHz to 1000 MHz (up to 1GHz), in the full VHF and UHF spectrum.

Over-the-air television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 and 216 MHz, and the UHF band, which comprises channels 14 through 51 and occupies frequencies between 470 and 700 MHz. These bands are different enough in frequency that they often require separate antennas to receive, but the RedZone Receiver covers the entire VHF and UHF TV bands.

The VHF band is further divided into two frequency ranges: VHF low band (Band I) between 54 and 88 MHz, containing channels 2 through 6, and VHF high band (Band III) between 174 and 216 MHz, containing channels 7 through 13. The wide spacing between these frequency bands is responsible for the complicated design of rooftop TV antennas. The UHF band has higher noise and greater attenuation, so higher gain antennas are often required for UHF.
