I presently have three 4 element 20 meter Skywalkers assembled and waiting to go up and I was wondering if anyone has optimized these antennas? They will be stacked 32/62/102.
John, I would be suspect of stacking 3 20m antennas so closely. You might actually be better off with only two antennas at 50' and 100'. This is a perfect example of where little time modeling may be worthwhile before you actually put any antennas up. BTW, the 20-4CD is included in YO7's database. The single Yagi model doesn't look too bad but it will definitely change when stacked. The more important question is what stack spacing you should use and whether you are better off with 2 antennas instead of 3. Modeling will answer these questions for you.
