KR> ELT antenna

[Clayton Brod]

My ELT is a AK-450, I would like to mount the antenna some where out of sight,
however the instruction call for a 36 inch ground plane.  This is difficult to 
do in a 
KR-2.  What are some solutions to make a acceptable installation? Is a 36 inch
ground plane standard?
Thanks:
