FYI - The antenna that ships with the ACK 406 will not fit under the empenange fairing, wont fit on the turtle deck and is too big for cockpit. You need a whip antenna that can be flexed.

Subject: ACK 406 ELT in an RV-8
I would like to purchase an ACK 406 for my newly finished RV-8, but need to use a different antenna. The 21 inch 70 degree antenna will not work on an RV-8. Many of the pilots in the RV-8 community are looking at the ACK 406 ELT and we all share the same problem. Because the Canopy slides back all the way to the tail, you can not place the antenna on the aft turtle deck. You either need to place it somewhere in the cockpit or under the empennage fairing.
The E-01 antenna was ideal and has been installed in multiple locations in an RV-8. I understand that you can not use the E-01 with the E-04.
Someone mentioned on one of the forums that there is a COSPAS/SARSAT whip antenna ( Dayton-Grainger), about the same size as the one that was shipped with the E-01, but I can not find one.
Can you provide a link to a a COSPAS/SARSAT whip antenna that could be used with the E-04? I will then be prepared to submit my order.
Much thanks.
