I am experimenting with reusing an old satellite dish to make a directional antenna for monitoring an 800 mhz P25 system. I live within 6 miles of three different tower sited for the same system and about 15 miles from a fourth. I get all kinds of gabled audio that I am guessing is coming from receiving two or more sites just milliseconds apart. (forgot the term) I am trying to get to the point of picking up only one transmitter site. I carefully measured the location of the center of 3 LNB so I could place an antenna at the same position. I then cut the LNB's off and a portion of the base they were mounted on. I then made a bracket to accept an NMO mount and placed an 800 mhz whip antenna on the bracket in the same location as the center LNB. I will drill completely throught the mouinting beam and run the feedline (LMR400) to the antenna and carry it below the mounting beam. Anyone have any ideas or suggestions good or bad? This is an experiment but if it works I will use it.
