The decision has been made – a 50ft/16m Rohn 25 tower and Ham IV rotator are on order and will be installed here sometime during the month of July.
I have about 5 days to determine which antenna will be held aloft and have narrowed it down to four but the real decision is – Yagi or quad?
All three of the Yagis are very similar in characteristics and I doubt any difference could be discerned in their on the air performance. Yagis are low maintenance antennas though – put ‘em up and forget about them for several seasons. I’m not sure that’s the case with quads.
In the quad’s favor are its light weight, small wind load and small turning radius – and better performance. The tower’s installation site places it 20 feet from a sweetgum tree so several branches would have to be removed tower-side for the Yagis…but not the quad (yet?). Fortunately, the tree is at a slight angle so the higher parts are farther from where the tower will be.
Also favoring the quad is the fact that is isn’t necessarily stuck at being a tribander. Elements can be added for 12 and 17 meters. Weather isn’t a factor here as icing would never occur. And finally, an additional element could be added to the quad later, making it a 3 or 4 element antenna with performance far exceeding that of a similar Yagi.
But besides possible maintenance issues is the fact that a quad would require a remote switch to enable selection of driven element based on which band I was on.
