I couldn't agree more with your observations. I think the commercial nature of the cataloge designs was one of the points Tom, N4KG was making. My comments, on this, were directed toward amateur use

Hi Saad, For your tower, placing the antenna at 36' will be the same as having 1/2 of that area at 72'. You need to add the mounting hardware area. You didn't ask for the rest of this, it is only for

Hi Jerry, Nope, that's not what was meant. Most towers are designed in accordance with published specifications. Amateur antennas are not. The tower guys are using projected areas because that's the

Hi Bert, Bummer, I hate it when this happens! The material in your cleaner has obviously attacked the coating. I'd wager a guess that the coating on the MN-2700 is an enamel. I've got one, so I'm kee
