Wow, I'm curious about that.  I just bought one of those.  
Haven't even put it up yet.  Didn't know adjustments were 
possible with those antennas.  Thought it had to do with the 
hight of the feed point whether or not you can put each leg out 
straight and other environmental or space factors like trees or 
other objects in the area.  Also, does anyone know if you can use 
one of these antennas on 60 meters? Jim WA6EKS

Subject: ALPHA DELTA DXCC Antenna

Do any of you guys have the e-mail address of the Technician at 
ALPHA DELTA
for info on adjusting the ALPHA DELTA antennas?  I had it for a 
long time
but have lost it somehow.  I would like to get some info on 
adjusting the
10 and 20 meter bands on my DXCC antenna.   If you have it, 
please e-mail
it to me.   Thanks much,
