What you are trying to do is minimize common-mode currents
between the choke and the transmitter. On the eznec.com
web page, Roy describes an inexpensive method of detecting
common-mode current amplitude using a simple toroidal pickup
coil. You could actually measure the relative effect of
your RS RFI devices.
