[amsat-bb] Simple 2.4Ghz helix plans?

[Michael Tondee]

I threw this out there on the eham satellite forum looking for answers 
but I'll try here too.
I'm looking for some fairly simple plans for this antenna. Everything I 
find either seems to be intended for WiFi or if it is ham related is 
full of mathematical formulas to figure length, diameter, spacing etc.
Math was never my strong suit so I'd prefer to find something with the 
actual already computed dimensions clearly stated. Preferably in English 
rather than metric measurements. I found an article in the May/June 2008 
AMSAT Journal that looked promising but there are no hard numbers, just 
the formulas  and I don't have a calculator capable of some of the  
computations, much less being able to work them out in my head. Been a 
long time since I was in school!.. hi hi... I have a downconverter I'm 
not sure even works and I don't want to spend a huge amount of time and 
trouble to be able to test it.
Tnx and 73,
Michael, W4HIJ
