Mounting an ELT in the Cub

The question came up recently as to where the ELT should go. I don't have an opinion one way or another, but this is how it's mounted on Zero Six Hotel:

As you can see, it's on the port side of the baggage compartment platform, behind the rear seat. The antenna comes up through the same platform and is secured with a plastic wire-tie to a frame member.

The control switch for the ELT is mounted on the panel for the mag switch, where it can be reached from either the front or the rear seat.
