At 1 your mic diaphragm would be at the same level as that straightedge.

And if it's 1.2, you are about the same as the Telinga, mic diaphragm 
between the straightedge and the dish, close to the same ratio. And we 
have a problem in that your large dish and the Telinga should have very 
similar gain curves. And that something else is at work.
