Hello everyone. Since having built my own DBGH and being able to reliably get nearly every station possible in my location (stations about 90 degrees north are blocked by a hill), a friend has asked me about his location. I'm fairly sure he doesn't want to bother with a rotor and he doesn't have to contend with the hill. So, what I'm asking is what would the pros and cons be of joing two UHF antennas at approximately 90 degrees apart? I know I need equal lenghts of coax from each one and (like myself) he'll need a preamp. I also understand I need to seperate them by 3-4 feet. I was just wondering how it affects performance.
