Hi Doug

ie like half a rhombic?

I remember the ARRL antenna book has a graph of wire wavelength vs gain/lobe
performance. Cant imagine it being to much more difficult than that.

Possibly a websearch on rhombics? Might cover the development/theory.

http://www.mindspring.com/~cummings7/rhombic.html has a link at the end to a
Windoze pgm that calculates best wire angles... I didnt try it...

Cheers Bob VK2YQA

I am looking for something on the web that describes the optimum
angles between wires, etc. I am not talking about inveted dipole
beams, but a pair of horizontal wires (or sloping wires) that are at
a 30 degree or so angle, usually fed with open wire line.

Thanks
