[TowerTalk] TH-6/DX/DXX

[Gene Fuller]

Can anyone tell me/us the differences between the TH-6, TH-6DX and TH-6 DXX. From the DXX assembly instructions and various ads all I can see is that the DXX has the more solid boom/mast casting, rather than the stamped metal like the element/boom supports and some details in the umbrella guy. Perhaps something in the tuning, element spacing, trap design  ??
