Hi all,
I'm about to embark on building my first pvc sub. Just throwing ideas about in my head at the moment, and collecting useful parts but I've just had a thought... I intend on using the sub in a canal that runs close to my home. This canal however, has a huge natural iron oxide content coming from the iron ore mines, so much so that the water has a real brown colour.



The thing thats worrying me is how will this large amount of 'metal' in the water affect the radio signal? My first thought was that it'd behave just like normal water, i.e. not transmit the signal all that well, now I'm starting to wonder, would the water actually act as some kind of huge antena and either transmit the signal or kind of amplify other signals and so mess with the signal I'm transmitting?

Any thoughts on this would be very much appreciated
Karl
