Dear Robin,
Why not thinking designing and do it yourself ?
Have a look to this marvelous website (and its "QHA Calculator") :
http://www.jcoppens.com/ant/qfh/calc.en.php
I made one UHF QHA following instructions ...
Works fine for (nearly) 0 Euro and 1 day of (enjoyed) work !!
Best 73 de IW2NMB, Florio

I'm sure this has been asked before so sorry in advance for the repeat......
Can anyone send me a pointer to the dimensions or construction details for a
helix for Mode S. I did a google search but it didn't turn up much.....
probably better to send to me directly rather than spam the whole group.
Thanks
Robin
