- AbstractIn this paper, an array dipole antenna adaptable to VHF and UHF bands was designed and constructed. The dimension (length and spacing) of the parasitic elements (directors) were determined: the longest length being 17.0cm and the shortest 5.3cm. The widest spacing was 3.58cm and the shortest 1.27cm. The characteristics of the antenna were determined at a frequency of 189.5MHz. It has an input impedance of 96.72Ω and a gain of 2.15dBi. It performs optimally in frequency range of 60MHz- 300MHz as attested using TV (receive only) monitor. It adapts favourably well to the VHF and lower UHF bands.
