The only problem we have is we have to elevate our spitfire callers to get reliable remote function due to poor remote range. I have mine on a small tripod (probably a foot tall or so) It works reliable at about 30 to 40 yards with the tripod. It doesn't seem to make a difference if the caller is in the open or not. I have called them into plowed fields really with not much hesitation. I do use a mojo decoy, but I always have it set up next to it. The truth is that it would be harder to sell the higher end calls if the lower end calls performed just as good as the more expensive ones. A factory installed external antenna would correct the remote range issue. With this said, I like my spitfire. It works good for the price, would just like better remote range. Thanks for the tip on adding a wire, does anyone know if you can add a folding antenna similar to the ones on other callers to it?
