(much shorter than VHF waves), with enough power or wattage, they travel better Australia. Antennas are small and amateur radio equipment for the UHF bands is compact and widely available. If you search for reviews on these same radios, you will find many disappointed people saying they can't get anywhere close to the advertised range. In the United States, the frequencies used for these systems may be grouped into four general bands or ranges: low-band VHF (49-108 MHz), high-band VHF (169-216 MHz), low-band UHF (450-806 MHz) and high-band UHF (900-952 MHz). and receive transmissions from the first antennae to the second antennae Very high frequency is the type of radio frequency electromagnetic waves that range from 30 to 300 MHz. System Specifications System RF Carrier Frequency Range 470-952 MHz (available frequencies depend upon applicable country regulations) Working Range 150 m (500 ft.) under typical conditions; 500 m (1600 ft.) line of sight (NOTE: Operating range depends on many variables, including RF signal absorption, objects both indoors and outdoors.
