Usually there's nothing to tune. If it's a Mosley TA-33, for example, they sell that as a rotary dipole as model number TA-31. It's just the driven element from a TA-33.
"Tuning" is accomplished only by adjusting the lengths of the aluminum tubing, which are adjustable by design. All you'd really need is a bracket to mount it on a vertical support mast as opposed to the original horizontal boom. Such brackets are available from DX Engineering and elsewhere. Most Mosley triband traps are 10/15m traps built into a single device on each side of the element. Piece of cake.
