i was just wondering what would be the pitfalls of fitting a fixed vhf radio to your yak would be i have been looking at the The IC-M401 it seems to have been designed to withstand water and is made for small boats and ribs it is very small in size and may be a good solution on the yaks .
being so low on the water - i reckon you would an antenna. Silva do a similar one of these sets and claim waterproof qualities but as we know these claims need proving like martin says a proper and regular dunking- terry ask them for a set to seatest on a kayak if they are confident enough its suitable for that.
did you say product review George on the icom 4001 ill get on it .it would need an Ariel .the set claims to be waterproof here is a part from icoms description:The IC-M401, together with its optional DSC controller (DS-100) is rated JIS-7 submersible and is really ideal for small boats, like RIB's, where space is at a premium and where water ingress on communication equipment has been a traditional problem: it would give extra power for those little bays where signals from handhelds tend to bounce off the cliffs it may be that a fixed units signal would also bounce off the cliffs but i just thought that the extra power may help a bit its actually cheaper than the m71 i haven't had a proper look at prices but the first site i looked at sell it for £160 +vat . its just am idea with the new generation of kayaks now for sale most of the manufacturers are putting ample flat surfaces on the boats so mounting would not be a problem .its just a thought that i wanted to explore .
