[TowerTalk] Yagis stacked over Moxon Question

[Marc Willis]

I am installing a 40 meter Moxon and want to stack a 4 element 20 and 4
element 15 over the top of it. Would anyone have information about antenna
spacing differences from a conventional all yagi install vs a moxon / yagi
combo install?

Coverted Hygain 402BA to W6NL MoxHat  below a 204BA below a Force 12 EF415
Appreciate the help.

Cheers and 73 Marc
