Just a tip to you all, When putting your ST16 into your foam insert, MAKE SURE you slide it in it's spot facing down! Antennas and all go downward, not up like you would think , to not put weight onto them! There are circular and square cut outs for all the switches and antenna's and the top goes over it!. Mine came shipped with it facing upwards, and the foam top half covering it pressed onto the mushroom antenna and snapped it off, not on the thread on sdc connector(luckily) !, but on the swivel connector of the female sdc screw on ! Just a fair warning to save you heart ache my friends!
