Have 2 KG905G radios, Ordered both of the Nagoya Antennas the 771G and the 72G, Range for us went from3/4 mile to almost 2 miles while testing in our area. YMMV. Going to order a base antenna and get it 30 feet in the air and see what kind of range we can get with the handhelds. When money permits look into getting a mobile or possibly a used Kenwood or Icom.
