I have plans to tin foil my Gecko - instead of course

I suspect it's a liability thing. I have never heard of a case of physical damage from VHF transmissions (not that I've looked all that much.)

You're right - You can't be 10 feet away from an antenna on a small boat, so that's kind of impractical. Realistically, you're not going to be transmitting all that much (well, I don't anyway), so I can't see it being all that much of a risk.

The frequency of marine VHF (156MHz) and the ERP of most antennas mean that there's relatively little to worry about.

There's probably more dangerous rays emitted from your modem at the side of your pc.

I remember the old CB radios used to light up a fluorescent light tube near the aerial.... Just like Star Wars.

Thanks for all replys a s been said not much transmission time so should be ok

I would have thought a handheld close to your head at 5W was more of an issue than 25W from an aerial probably high up on top of an A Frame

One reason why hand helds were only supposed to have a maximum output of 5 watts !

That and the fact that much more power would drain the batteries.
