    Optimal design and fabrication of a wideband antenna for terrestrial DTV reception
    (U. P., 2016-10) Agubor, C. K.; Onwumere, C.
    Optimal design and fabrication of a wideband antenna for terrestrial digital TV (DTV) reception is presented in this paper. Reception of poor digital TV (DTV) signal using Yagi antennas supplied by cable providers in some suburban and rural areas in Nigeria has been a major concern to subscribers. This problem could be solved by the use of high gain antennas such as the one presented in this paper. In developing this antenna, NBS 688 technical notes and antenna design curves were applied and the resulting antenna estimate was modeled, simulated and optimized with 4NEC2 antenna design software. Optimal design verification was achieved using EZNEC v.6.0 antenna modeler. On testing after fabrication, received signal strength was 60dB compared to 45dB obtained with the service provider’s conventional Yagi antenna in position. A better picture clarity was observed owing to the15dB increase in signal level.
