    Is there any ways that an omnidirectional microwave signal (digital) could be affected by power lines 25 feet away from the transmitter? I know any electrons moving into a conductor creates a magnetic field but could it affect a microwave signal?

    If your microwave signal is emanating from a device that concentrates it into a concice beam, then yes..

    Similar to how the electron stream in a CRT is affected by the magnetic fields in the yoke, the corona around power lines could conceivably bend the microwave beam

    Powerlines won't affect an Omni running somewhere in the GHz. In fact powerlines won't affect much in RF unless we're talking low frequencies (KHz) or HV powerlines - and they won't be 10 meters close to *anything* due to regulations.

    If there is any effect it's more likely to be from the large metallic stucture rather than the fact that it happens to be power lines. You could potentially get weird multipath effects.

    Yeah plus I'm thinking of all the RF being used by EMF's, cops etc... in a big city. That would create a mess
