eXRS TWO-WAY RADIO RANGEEXCEEDS 100 MILES!That’s a bold statement and true, but of little practical value to the user.
The actual range of eXRS and all other UHF two-way radios including FRS and GMRS (walkie-talkies) is effectively the same, regardless of transmit power. The total range is greatly diminished by the effects of the atmosphere, trees, buildings, hills and all other environmental conditions in the area of use. Portable UHF radios are effectively straight-line communications devices. It is the path that establishes usable range, not the transmit power.
The Earth is not flat. Even the curvature of the Earth limits the straight-line path. The average curvature of the Earth dictates an average maximum range of 6 miles.
There are certain conditions that will extend the straight-line path to more than one hundred miles (mountain top to valley, for example) and there are many conditions that will obstruct the straight-line path to less than one mile.
Shorter Range Conditions
Longer Range Conditions Beware of advertised range claims. Advertised range has grown over the last few years from a couple of miles to 30 miles and more in an effort to distinguish product pricing. All good quality portable UHF radios, regardless of range claims, will perform essentially the same under the same conditions. It is unlikely a user will normally experience a set of conditions conducive to long range operation, but under those conditions, radios with advertised range of 2 miles will perform equally as well as those advertising greater than 30 miles. Realistically, under most conditions, typical range for all eXRS, FRS and GMRS radios will be a few thousand feet to several miles. eXRS radios have been independently tested head to head with the top of the line GMRS/FRS radios and up to five Watt commercial radios and the results demonstrate that they are all range equivalent.
