> RCS8V not grounded....
Many of us view this as a feature because without modification the RCS8V is
readily used in phasing circuits for two yagi stacked arrays, and in low band
setups like the K8UR / K3LR vertical dipole arrays which require open rather
than shorted lines.
See the classic NCJ articals by N4SA (vol 8, issue 5, page 7) and K8CC (vol 16,
issue 1, page 17) for examples or U/L/B and other cool phasing circuits. For
those without NCJ access, there is a JIF of the "classic" Upper/Lower/Both
circuit on VE3GK's web page:
For two-stacks the U/L/B switching method using an RCS8V plus some coax is
easy, cheap and pretty much bullet proof.
