I ran across that same bit of information earlier this morning and found it informative.
I had an antenna that had no gain at all, except when two or more of them were stacked. It happened to be a horizontal/vertical antenna, so, based on the above link, maybe my antenna did have gain after all.
"... maybe my antenna did have gain after all."
Gain with respect to what reference?
Rich: "Gain with respect to what reference?"
I'm thinking back.
I do remember that I had a reference but am having trouble reassembling the experience...
My big problem here is memory. My guess might not be what really happened, so I'll say some words and hope to come close.
It was a part 15 certified transmitter, possibly a C.Crame FM first with it's own antenna fully extended... let's guess... vertically.
3-meters away was the spectrum analyzer and I made a note of the reading.
Then I minimized the telescopic antenna, ran a clip lead 2-inches to the center point of an L-shaped wire taped to the wall right at the elbow... what I call a "Mid-Fed L".
The reading at the analyzer was the same as the previous reading, which is my basis for saying "no gain".
That's as good as I can do in reconstructing what happened.

Thanks, but do you suggest that your recollections actually prove your point(s) to those who read them?
Upon retrieving more of my antenna experiment memories from The Cloud I have restored more of it.
My testing went on around the same time as Tim's F.I.M. measurements of FM transmitters, which puts it in the summer of 2015. I posted liberally alongside Tim's frequent reports, therefore for anyone seeking details of results and discoveries it's only a few scrolls away.
Crossing Paths -- Right after writing the previous I find a new question from upriver where Rich resides: "...but do you suggest that your recollections actually prove your point(s) to those who read them?"
Carl's reply: Ask them.

I asked you.
Wouldn't you serve yourself better to the readers here to answer that question as it applied to you?
Why I was right apriori...
Rich asked whether THEY (the readers) could derive "proof" from whatever I said.
Directing Rich to "Ask them" couldn't have been more appropriate.
His saying "I asked you" risks short circuiting the conversation, in that my response fully honored Rich's having asked me.
