Buy Midland Antennas for 2-Way Radios with removable antenna radiator and stainless steel construction. The reason for selecting the 5λ/8 wave ground plane is that for a simple single element antenna it appeared to have increased capture aperture when compared to the standard λ/4 wave length ground plane antenna and has a relatively low angles of radiation in comparison with other similar antennas. It will receive both digital TV and HDTV programming at a reception range of up to 100 miles. A suitable antenna is vital to good performance, and getting your installation "peaked and tuned" can make a considerable. CB and amateur radio systems work best when the antenna system’s impedance closely matches the transmitter’s out-put impedance. There are other antenna options at your local parts store (windshield antenna kits, shorty matched flexi antennas, etc). You have just built a Vertical CB Dipole Antenna, that needs NO Grounding, or other constructs, to work. There is much confusion concerning the proper length of coax to use with your cb / ham setup.
