Bob is planning a new L/S redesign.  Before I pick up my hack saw I would like some opinions/advice etc.  The dish-a 54X48 inch prime star. The feed -a short helix for L & S side by side in line with the fan pattern.  I beleieve W0LMD tried co-wound helixes with mixed results.   On the same boom is a 2M & 70cm yagi.  With all this antenna and counter weight is it too much for my G5400 elevation rotor?  Plan "B"- use a actuator similar as described in http://www.qsl.net/sv1bsx/actuator/actuator.html  .  I have some actuators and a lot of hacksaws and I'm not afraid to use them.  With only 10watts and some hardline I feel this dish might be necessary for a HEO on L band, and I might as well use it on S.  I also have a 12foot TVRO but that's another story (project) for another day.  As always your opinions/advice  even ridicule is appreciated.
