I use FPVLR antennae and have the vTX pentalobe one hanging below the landing gear. Also I transport my kit around in a back pack, and things can get a bit squashed in there. For these two reasons I have been looking at ways of protecting the pentalobe and pinwheel from accidental damage. I am really crap at golf, but have discovered that these antenna fit really nicely inside a plastic practise golf ball. I will prototype one up and see how it works out.
