I have mentioned before about my occasional operating from the YL's QTH and the high noise level there. In some ways I felt the noise was worse because I was using a vertical antenna (The pro whip) although the noise level was a great deal lower when using the same antenna at my own home.
So what is the cause? As we all know there could be many causes-Plasma TV's, internet over the mains and so on. But in the middle of the housing estate and very close to the house is this:
It must be 25 Metres or more high and is covered in all sorts of antennas from what looks like VHF beams and verticals to Microwave dishes. I have no idea what frequencies are being radiated from this mast but I think that at least part of the noise problem may be coming from it. I am just glad its not at the end of my garden, on the other hand I would like to be able to run a wire dipole from the top of it!
