[VHFcontesting] dual polarized Quagi

[Cal Zethmayr]

My boom will be a fiberglass 25 foot length of 2 inch high pressure gas line. it is very heavy duty but very light to hold.  less than 5 lbs.

I would use a set of vertical and also horizontal elements.  I'll use a drill press to drill the holes.

I'd size the vertical elements for the upper end of the band where most repeaters and mobiles would be and the horizontal elements for the lower end of two meters where most cw and sideband activity is.

One of my helpful local elmers suggested I could use a full wavelength of ladder line from each of the feed points on the driven element to the relay box that would be on the bottom of the boom.  The relay would short the feed point of one while the other would then feed the coax down the tower 125 feet to the entrance to the shack.  He thinks that the shorted wavelength would thus be tansparent to the tuning.   

Anybody have any comments?
