>>The trick is to realize that it's not *perfectly* point-to-point - the beam shape isn't a cylinder, but a very narrow cone. The end result is that by the time it's taken a 15 or 20 mile trip tower-to-tower, there's probably some signal down at the base of the tower too. Also, the physical security of those things usually sucks, so if you wanted to climb halfway up the tower with your dish, you probably could. Remember, those relay towers are usually in the middle of nowhere, so it'll take a good 15-20 minutes for cops to show up - plenty of time to sniff lots of interesting data... OK, I've already mentioned that these will be on state police towers in Lousiana. Do you really want to set upo your own microwave receiver at the base of Office Bubba's station? Be my guest.
