Shielding?  The trick to a good RF ground is to avoid resonant lengths at
which the ground lead presents a high impedance to the radios.  Most above
ground shacks have long-enough ground leads so that they approach this
situation on one or more HF bands. My station is moderately RF-y on 15M for
this reason.

Why would you want to run the tuner on the Mark V when feeding a Quadra
anyhow?  Surely the input SWR is pretty low on all bands.
