The logic sounds good. If a fuse blows the panel then you could be in a bit of a situation, so having the vhf tied directly to the battery would facilitate using the despite the power outage.
I just don't like connecting anything directly to a power source without some kind of blow point in line. Our vhf has an inline fuse at the back of the radio, so it would be reasonable to make the direct connection.
If your electrical system is reliable, I don't think it matters much whether power to the VHF goes through the main distribution panel, or bypasses it to the battery. I agree there needs to be some sort of over current protection in series with the radio. The quickest and cheapest conventional way to do that would be to install the included inline fuse near the battery end of the VHF power lead. Think of all wire between the battery and the first fuse/circuit breaker as unprotected, and capable of starting a fire in the event of a short circuit with anything connected to the negative buss.
Okay - sounds reasonable. And yes, I see there is an in line fuse in the power lead. I just didn't know if there were issues with electrical or electromagnetic interference per se.
