Yep... a SteppIR AND one of these...

I see the gain figures on that beauty and I puzzle over why the dBd and dBi
gain figures are so far apart -- about 7 db. I expect a difference
somewhere in the 2 - 3 dB range. IIRC it's 2.2 dB. What am I missing?

Before I sent this, I did a Google search using some of these terms and
discovered "ground reflection gain," a term I have never seen before, except
in connection with EME with the moon near the horizon. Is this a realizable
gain or damnable inflation of gain numbers?

TKS.
