Rich,

I don't use any chokes on my 160m 9-circle RX array....located
about 900ft from the shack. 

Chokes on the lines of your antenna couldn't hurt.  Snap-on chokes
may not offer worthwhile resistance.

8, 50-ft radials each element.  "W8JI" elements.   No Hi-Z elements. 
I used his "touch-the-feed-line-to the radial ground" to see if
there is any change to the impedance at the antenna.  NO changes noted.
I used 3/4-wl lines on all elements.

RG-6 coax.  RG11 to shack.  Thru-the-coax remote control.  See ON4UN's
DXing book
for a couple of photos.

73,
Charlie, N0TT
