If you can achieve real noise margins of 20 dB or greater at the receiver, you will have very few, if any, visible impairments to reception.

Notice I'm not referring to a particular signal power level... A strong signal mixed with interference, noise or distortion products may not be receivable. A weaker signal free of interference, noise or distortion may provide 100% reliable reception.

There is more to reception than mere signal strength.
If the well is dry and you don't see rain on the horizon, you'll need to dig the hole deeper. (If the antenna can't get the job done, an amp won't fix it.)
