Using a 1:1 current balun at 50 ohms, I would find that it is difficult to
measure the loss on the HF bands. A series of #43 beads (15 to 25) on a
piece of RG-213 or RG-8 will have no more loss than the length of the coax.
And It just might stop RF current on the shield from flowing back to the
Orion from and amp/tuner/antenna combination.
