Finished up the ELT installation by riveting the mounting platform to one of the fuselage cross braces (in the front) and the fuselage floor (in the back). With the bracket already attached to the mounting platform, it was short work to strap the ELT into position and hook up the antenna. Last thing to do is secure the antenna cable and run the connection up to the ELT control head on the instrument panel.
