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 s
hort helix for L & S side by side in line with the fan pattern.
If you mount them side by side, there will be a compromise as there is only
one focal point.
The concentric feed can be made to work as long as you have some filters to
keep the 1.3G signal out of the 2.4G RX.
Here is a good page on the topic.
