Their marketing is rubbish, btw. Any standard "whip" type

A lower frequency requires a *shorter* antenna?? I thought it would
have to be *longer*. Please explain.

Sorry - I got it reversed. but the theory is the same - find
the right length and make it so. Then aim.

Sorry, but I am having trouble figuring out how to extend a whip
antenna to a length longer than its maximum. Hints?

Stick a saucepan lid on the end (capacitive loading) or a crock clip
with wire attached. The possibilities are endless.
