Hi Bill,

When camping or during Field Day it should be possible to use two of your 
gizmos to make a short boom yagi or phased array. My first 40m beam in VE2 
land had 22ft lengths of bamboo on which the normal mode helices were 
wound - worked like a charm once tuned.

Good luck with the commercial folk.
