-- The only way to shield the house is to wrap the house in foil or metal screen. But if anything passes through the shield ... like electric utility service lines, telephone lines, TV antenna, water pipe, gas pipe, etc. ... the interference can ride in on any one of them. -- There are electronic things you can do at the input to your TV or radio to get rid of interference. But if you know the source of the interference, then it's not your responsibility to do them. -- A properly operating CB radio does not interfere with TV or radio, no matter how near, not even in the same house. The owner/operator of the CB radio is legally required to make sure that it's operating properly, i.e. in the condition it was in when it came out of the factory carton. A CB radio that has been jimmied, opened, altered, or connected to an external amplifier, is operating illegally. You can talk to your neighbor if you feel like it, but you're under no obligation to do that. It's very easy to file a formal complaint at www.FCC.gov . It's entirely your neighbor's responsibility to clean up his operation, or else lose his license, or else pay a fine, or else face imprisonment if he decides not to be reasonable.

Additionally, ensure that the power supply is of good quality and can provide stable power output to prevent any interference with the radio signal.
The whine probably comes from the alternator. You will need a supressor on the alternator output. Another way, is to use an in line filter in the power supply, to the CB, to stop interference on the power supply from reaching the radio. You need an auto shop to check the alternator. The in line filters can be got from radio Shack and look like an in line fuse.
