I can add a little information that might be helpful.

When considering a receiving antenna, the single thing you need to be
concerned about is signal to noise ratio. Unless your antenna is
exceptionally poor and/or your receiver exceptionally noisy, making what
you receive louder is just a matter of turning up the volume, or adding
an audio amplifier if it's not loud enough. But it won't help you hear a
station, because it and the noise will get louder in the same proportion.

I differ; although, I can understand why Roy would reply in such a
simplistic manner ...

If the antenna is resonate, matched to its' load, and is not using lossy
construction practices--a very magical thing occurs. And, in such a
situation, it appears as if a wire runs directly from the transmitter to
your antenna. Nicola Tesla first documents this, then others ...

However, most give up before they obtain the knowledge and construction
practices which produce such antennas--and, indeed, if you wish
broadband antennas, no matter how you construct them, they will only
produce this performance on a narrow band of frequencies, or perhaps,
just a single one ... but, they can be constructed to preform,
reasonably well, over a broadband of frequencies or even bands.

If you have immense focus, devotion to the construction of antennas, a
reasonably astute mind, and the necessary skills, a willingness to
construct until you have that "revelation"--the realization of all this
awaits you. :-)
