    Thanks, I looked all in that area on my fuselage and there is no plate. My kit was delivered in June so I thought it would be up to date. I will just have to do something like the others on this thread.

    This is how I mounted my ELT and put the antenna in the vertical stabilizer.

    Two more things to think about. If mounted high, for sure easier to maintain, but if it should break loose during a crash, it could become a lethal missile - remembering the EAA accident investigator from Alaska who talked about a fatality who had a fishing pole protruding from the back of his head - otherwise survivable. If mounting low the same thing applies, but for a different reason, If the mount won't sustain the G forces - mounted high or low - in a crash, the antenna cable might break from the unit with no transmission.

    I don't know if Adel clamps are designed to withstand heavy G forces applied by heavy equipment. I have seen them break supporting the ignition module over time. Our emergency Landing (crash) was a half mile from a Fire Station and the property owner was on the cell phone within minutes, but if we had lost oil pressure a half hour later, we would have been at the crest of the Sierras. We didn't need the ELT where we were, but if there, our lives might have depended on it functioning correctly.

    Internal antenna - after the Emergency folks arrived at our crash site, the first thing they asked is where the ELT was. They wanted to shut it off - they work.

    I used thicker steel clamps (Ace Hardware, not Mil Spec) that are much stronger and less susceptible to fatigue.

    I'm a ELT and SAR products specialist too and i would add that in most part of the crashes, the coaxial cable is broken and so no transmission...
    If you buy a new one take one with external AND internal antenna so you will be rescued ;-)
