Petegill, ultimately I'd say it boils down to dealer's choice. There are pluses and minuses for both a mast mount or a stern rail pole mount. You'll get a zot more range with the mast mounted unit as a function of it's height above the water. Unless you've got an open array, I really doubt you'd ever have issues with the jib hanging up on the radome. Not saying it could never happen but I don't recall anyone ever mentioning that they ripped their jib on the radome. Don't forget, the domes are round with smooth sides so I really can't see what might grab the jib. But then again I never say never when it comes to boats.....
