Are there some professional RF folks in here or even someone who just knows this, but would someone clue me in to how broadcast antenna towers work? The ones I am thinking of are the tall red and white painted towers, a few hundred feet tall at least, usually located on large (other than the tower and associated equipment buildings) vacant lots, guyed out like crazy, flashing red light at the top, but with obviously visible antennas. To complicate the question, I have no idea what station or frequency the ones I see every day operate on, so I apologize for the vague question. Is the tower itself the antenna, shunt-fed or some other way of feeding from the transmitter(s)? I admit I am clueless on this subject, figured someone here has got to know. Thanks!
