Since you are using a roof mounted antenna and are VERY close, I would
suspect that you might be over-loading the receiver section of the HDHR.
I haave a large antenna and I am over 30 miles from some of the
transmitters and it works well. So the sensitivity is high!
You might try an attenuator, or just a couple of splitters in a chain,
to chop down the signal.
