CB radio with expanded effective range - uses antenna diagram with zero node point to allow operation of closely spaced stations

摘要

The CB radio with an expanded effective range has the transmission energy focused in a given direction, the radio antenna exhibiting a zero node point in its radiation dia. to allow operation with a relative spacing between stations of between 10 and 30 metres, without interference, normally not possible due to the excessive antenna voltage. The antenna may have 2 antenna elements coupled via a line, with both the antennas of the adjacent stations positioned at the zero node of the opposing antenna. USE - For communication via closely spaced stations without interference
