A friend just bought the Maco v5000. He was using a magmount on a car for base and had no trouble with the neighbors. With the Maco up now ,he has bleed over on the neighbors TV and phone. It is up around 30'. My guess is that it is now even with the power lines. If this is the problem, how much higher than the power lines does the antenna need to be roughly to quit sending the signal into them ?
