Hatch Enclosure - Do magnets affect the radio signals?

I have been trying to find a way of sealing my hatch with magnets for enclosure, not only to make it waterproof, but also to be able to access the interior for lets say, battery change. I believe magnets are very useful in these kind of things. But before doing that, do the magnetic field that the magnets create affect the radio signals that goes through the hull to the receiver? Its been troubling me for days, does anyone know about this subject? :cool:

Hi Captain:
No, there is no effect of a magnet on RF at the frequencies we use aside from them being a metal object. A permanent magnet is a stationary "field" and it would have to be a moving field to ever be considered. Magnetic latches are common in both transmitters and receivers as part of the interlock protection, ie. they are used on access doors to trigger shutting off power. You can also buy "Mag-mount" antennas for you car when you don't want to drill a hole.
