Directional patterns can be accessed, displayed visually and edited if desired. Land Mobile stations with UHF television channel assignments automatically appear in channel searches. Just enter in the geographic coordinates and type of station, ie. If an LPTV or translator search is chosen the program will also require an input of antenna height and power. Referencing a state ordered indexed database, the program uses a geographic grid system to pick out only those states from the database that are within an appropriate distance.
Most searches take only a second or two to complete.
When the computer has gathered the data from the database, you then have completed a search of not one channel, but all channels at the search coordinates. You can page through each of the channels from two to 69 as easy and as quickly as you page through the pages in a book. Once you have looked at a given channel study, you may recall it to the screen at a later time simply entering its channel using the channel scroll. A listing is printed for all those stations having a distance and frequency relationship. The listings include, power, antenna height, geographic coordinates, bearing and distance from the reference and the distance to the interference and protected contours, information regarding antenna polarization and beam-tilt.
