Exactly. We're going in circles. They do NOT all supply a means of hanging vertically, only the "goofy" araingement in post 15, from ad literature. That is what they advise. The buyer needs to work this out before you put them on board. They figure we are all fishermen with vertical rod holders on the cabin top.
I changed the rigging on the Sirius C-1003 and made a bridle for the C-1002. And the Orion comes with a naging bidle, but it is bungee, when it needs to be non-stretch to reduce swinging.
Just pitiful, IMO. Good equipment made useless by poor mounting.
