I'm new to the forum and have a question. For the most part, I listen to public safety freqs ranging from 151 to 159Mhz. Can someone recommend a good high gain antenna for this band. Antenna would be mounted on a mast about 40 feet above ground. Cable is LMR-400, and a total run of about 75 feet. I was looking at something like an Antenex FG1520. Would this be a good starting point, or can someone suggest another option? Thanks.
