I'm looking at these GMRS motorolas, one is a t6510xmrs and another is a
t5520. Here's the thing: both have a power output of one watt, but one
claims to have a distance range of 8 miles, and the other 5. Is this BS or
what? Why would one 1 -watt radio have more range than another 1 watt
radio? They both have the same size antenna.
