Maybe you should buy an antenna, instead of trying to build one
.
There are many issues that affect
DTV more than analog when building an outdoor antenna.
Here in SLC, we get 22 DTV channels from 10 different full power stations. Three more full-power analogs have to "flash-cut" to DTV in February. There are, also, 10 LPTVs sitting on their various hands.
Nine of the stations....18 DTV channels of programming (8 in HDTV).....are available over DTV translator stations (200+) throughout the state. The translator engineers say that 3/4 of the state's 1000+ translators will have DTV on-the-air by the end of the summer. All the analogs that have DTV companion channels will then be turned off, starting 2-18-09.
