A ONCE-IN-A-LIFETIME BUSINESS OPPORTUNITY

With advancing age (70) along with accompanying physical limitations, I find it impractical to continue. Therefore, I have decided to offer for sale my Patent No. 5,841,406, entitled "CRITICALLY COUPLED BI-PERIODIC DRIVER ANTENNA", the "RAIBEAM" trademark, along with a complete package of engineering and production data plus assembly manuals, a detailed cost/materials spreadsheet, an inventory database, and this website with its hundreds of world-wide links and which maintains over 30,000 visits per month, in the hope that this superior yagi-style design will continue to flourish. 

The asking price for everything is $175,000 and partial financing would be available to a responsible party. My availability for consultation is also a possibility.  

Serious enquiries only. Contact: wa7rai at cox dot net.

To demonstrate the superiority of dual critically-coupled driven elements, I invite you to model a 7 element classical yagi design, and achieve equal or better results than what is illustrated in the plot below* 

7 element 6m Raibeam^TM: free-space gain and pattern

EZNEC 3D average gain: 0.999 = 0.00 dB (includes conductor loss)

*The EZNEC+ file for the above plot can be made available for inspection.
