[TowerTalk] A Question of GAIN

[Josh Logan]

Assume a person built a 4 stack of C3 Force 12 multi band yagis

The C3 is given 4.6 dbd net gain for 20m

IF stacked at say 35ft, 65 ft, 95 ft and 125 ft
What would be resulting GAIN?   

I would guess around 4.6 + 3.0 + 3.0 + 3.0 = 13.6 dbd net gain

Is this reasonable??  What is a good spacing ?  30 ft  ?
assuming 20m performance is important.
