In reply to GW7AAV:
My FT817, mic, power lead and rubberduck antenna live inside a plastic food (sandwich) box. I bought it from a supermarket a few years ago, it fits the FT817 perfectly for footprint and the mic and accessories fit in on top. The only downside is a little bit of extra weight. My FT817 still looks like new (in total honesty!)and is from one of the first batches in the UK. I don’t know why I carry the rubberduck antenna - I never use it!
I carry my SLAB in a ‘clip lock’ food container, this keeps the terminals safely out of the way of anything that may short them. Again, this was purchased in a supermarket and I managed to find one that fitted my 7AH SLAB pretty well. I drilled a little hole in the container to allow venting, but this is probably not neccesary.
I can really recommend food containers, they are cheap, very tough and come in a variety of sizes from tiny to huge! The ‘clip lock’ type are also pretty much waterproof.
I value the protection and convenience over the penalty of a little extra weight.
