In article , Ed Huntress says...

In any case, the point is that, in practice, you can get good performance in
receiving with very simple antennas that have unknown impedances, which
wouldn't work in transmitting without a separate matching circuit.
Relatively few receiving antennas are matched, unless they're also used for
transmitting.

I can recall that most of my receivers worked a *lot* better
when the antenna was tuned up to get good matching for transmitting.
A *lot* better. Like, they didn't really work at all unless
the transmatch was set right.

I think that probably most folks who say they are getting good
performance from a random length longwire are either lucky
or they don't really know how good it *could* be.
