I have a backyard that is about 140 feet long and 60 ft wide. Often random wire antennas are also (inaccurately) referred to as long-wire antenna.Long-wire antennas require a length greater than a quarter-wavelength (λ/4) or half (λ/2) of the radio waves (most consider a true long wire to be least one wavelength), whereas random wire antennas have no such constraint. For peak performance, a field of … 18 Item(s) Show. My driveway goes around the back of the house so it would be hard to run wire along the ground. The antennas commonly used for LMR—both at base stations and mobile units—represent only a very small portion of all the antenna types. ... L-matches are good for end-fed or coax fed antennas while balanced types are good for balanced feedline antennas. Resonant Antennas.
