Topband: Capacitive vs. Inductive Matching of Inverted 'L'/'T'

I used to use a slightly shortened 'L' with a small inductor at the base
until I was told by LA5HE that he could hear me on 80 as well as 160!
Using capacitor matching forms a low pass network which will reduce
harmonic radiation. The inductor method forms a high pass L-network.

BTW, why is it called a 'hairpin' inductor? Looks nothing like a hairpin,
or does it?
