(I can think of a couple of methods, but we'll use your brain for this exercise.)
:lol:
Well, the slinky would be similar to a twin line open feeder, only that the twin line feeder is normally housed in a can for the highest frequency required (short circuit). When the lower freq is chosen, the feeder is "released" from the can to provide a longer length.
Much the same as if it were a single line, end fed wire antenna (for restricted space).
As for the radiators, these too would need to be on a moveable horizontal mount.
Just like an adjustable pool-pole for picking up all the leaves (floaters) Ew.. :wink:
There by the slinky could be mounted around the pool pole with the required spacers?
Like I said Trash, you're doing my head in... but it is brain food you've provided!!!! :D

This is an example of a simple system using a 3dB hybrid.
The antenna type and feeder length don't need to be specific. The array is steered by changing the impedance of the load.
