Did some testing and I don't have as much directivity but I sure as
heck have plenty of gain with this setup. I might have to get a loop


Kurt,

Congratulations on your success.

Gain and directivity are related, Gain=Directivity/Loss, or in dB, Gain(dB)
=Directivity(dB)-Loss(dB).

So whilst it is possible to have gain without directivity (due to high
loss), the reverse doesn't happen.
