My problems are largely man-made noise from the plethora of solar inverters surrounding my house and secondarily a high-voltage power line about 1/2 mile away. The noise could be a lot worse though and using a horizontal dipole that is slightly farther from my neighbors' houses instead of mostly vertical antennas near one of the "chief interferes" has helped quite a bit. However there remains a certain amount of noise.
I have found the WiMo QRM Eliminator to be helpful. Its just a tunable canceller.
