I am interested in setting up GMRS repeater(s) in Delaware. I am located in Middletown Delaware (50 ft above sea level) with an active repeater and a 6 db antenna on a 64' mast. I have reached the repeater from my mobile from the Pennsylvania / Delaware border (Newark to Concordville) and a little North into PA, the Elk River in Maryland, Western Salem County New Jersey and most of New Castle County Delaware.
