..."Handbook Project".
Smart Alec youngster... by cracky "when I was your
age all we had were wooden cavities... and we
like'd em."
Some of the 1960's, 1970's and even into the 1980's
ARRL Handbooks had folded inductor band pass filter
projects. I built one of the 6 meter projects and
the darn thing worked really well for what it was.
But the Q of the entire unit wasn't even close to
what a true cavity might provide. But as a poor person
I had the chance to try it in different locations
to see where the best bang (location) for the applied
buck was.
I guess using an actual paper book for the building
material would have even lower performance.

On a different note, I found a dummy load built into
an old wood cigar box at the local ham flea market.
Laugh away but I'll say the builder at least put
household aluminum foil around it. I bought it because
he used true non inductive (expensive) resistors.
Life goes on...
