Finally got around to taking the pictures.
It's 3" ID PVC that I cut to length to fit my radio, PLB, and 2 lb bean bag weight. I cemented a round end cap on one end, and a threaded one on the other end.
The first picture shows a 2 lb bean bag weight, the HX870, and the PLB. I put the bean bag in first, followed by the HX870. I drop the radio in so that the rubber ducky antenna is oriented up towards the opening. After that I drop the PLB in so that it fits right alongside the rubber ducky antenna. Finally, I give it a few wraps of teflon tape and seal it up nice and tight. I then use two black nylon dog collars to attach it to my BCD back alongside my tank.
The second photo shows the configuration inside the cannister.
The 2 lb weight leaves it slightly positively buoyant so that if for some reason I were to lose it, it'll go up to the surface. I then painted it florescent orange to make it easier to see on the surface.
I also added my phone number to the outside of it, just in case someone were to find it, they'd at least know who it came from. I also wrote the contents of it in case someone found it and didn't know what was in it.
On my SAR card that I filled out with NOAA for my PLB, I added the comment "Survivor has portable VHF radio and will be monitoring CH 16".
