[TowerTalk] Stacking yagis

[Larry Banks]

Hi Vasile,

The best discussion I have seen about stacking is at Directive Systems: 
http://www.directivesystems.com/ .

The App Note is at http://www.directivesystems.com/STACKING.htm

This is really about VHF stacking -- but the theory would work for your 6M 
yagi over the A3S.
