        Longest TX/RX on this test was 2.82 mi over FRS & MURS. Base radio handling TX-ing is the Baofeng UV-5R with a roll up J-Pole. RX radio was a Yaesu VX-8 with a Diamond extended whip antenna.

              Flat terrain?

              East TN terrain, nothing flat about it. Notorious for difficult comms. The reason our distance was so short was we basically just ran out of time to go out further. And this was our first ever test.

              Delta of about 80ft. elev. from TX point to RX point.

                    Hi…all radio signals are basically “LINE OF SIGHT” that is the wrong concept to use. Most electronic technicians will tell you that RF (RADIO FREQUENCY) theory is largely a mistery to those that are not communications engineers.
                    NEVER believe the performance ratings listed with any radio equipment. Here are some basic examples of why.
                    If those 49MHZ Radio Shack kiddy walkee talkees worked “line of sight” they would work for miles, yet in some cases they won’t even work a coupple of hundred feet.
                    If the FRS radios on UHF worked the 10 -20 miles like the package advertised that would be all we needed, but in reality if they get over one solid mile, in reality you are doing great.
