ELT panel and antenna location

Postby kevinh » Mon Jun 13, 2016 2:41 pm

Hi ya'll,

Before I drill holes I'm requesting feedback :lol:. Two questions for the more experienced:

1) I'm thinking about installing the ELT panel on the bottom side of the right frontmost turtledeck former. It seems like it should be accessible if needed and not prone to accidental pressing. Does this seem reasonable to you? Here's a pict, thinking of putting it where my thumb is pointing:

2) On my RV I did the common/pretty approach of putting the ELT antenna under a fairing. However, now that ELTs have 406MHz it might actually be useful and out of caution I'd like to put the antenna externally. Just in front of the #4 turtledeck former is the only reasonable place I can find. Any other ideas?

In the perfect world I'd be able to sit in the plane and mock this up, but I'm building in a very small shop and one bay in a garage. To keep productivity high I'm trying to accomplish everything I can in the shop before moving the aft fuse to the garage for eventual final assembly so thinking about doing the ELT installation now.

That's exactly where I installed my ELT remote switch. Works just fine

I'm not so far along, but somewhere between or just in front of the v tail is where I thought might be the best place. Should work great if right side up, and maybe won't be crushed and still work if inverted. I'm looking at the ARTEX unit with gps broadcast, so I agree, the 408 might actually be useful if you ever need it.

And where I installed mine, too. Works just fine. Easily seen.

Hi kevin,
Yep thats a good spot! Thats where we put ours. We have a ELT tecnologies 406 mhz elt , antenna is a shark fin type mounted between the v tails. Couldnt have metal around it so we made the fairing out of fiberglass.
Someday need to head south to San Mateo to see your project. Im just up the road in SF for the summer.
Looks like your'e really making progress. U'r giving bryan a run for his money!
