Hi Jim and Readers,
My Dakota Alert works great, as long as I can keep the batteries fresh, I find that they really use the current up fast.
I did paint the outside of my "bird nest" box with paint that looks like bark and green leaf color that I purchased in the paint department at Wal-Mart. It really helps camouflage the box, and when hanging it on a tree, most people never notice it.
As for protecting the antenna, I covered it with 1/2 inch black adhesive-lined shrink tubing available from Mouser Electronics. By shrinking it on the antenna is more resistant to moisture, and it covers the shiny antenna and gives it better concealment.
I have also adapted and camouflaged another 2 meter band yagi antenna so that when the SHTF I can place the unit much further down the road and yet still hear the signal in my receiver. - Dave in Oregon
