[TowerTalk] DC grounding of parasitic eles with insulators ?

[Jim Thomson]

Ok,   the  ref  +  dir  on  my  modified F12 340N...3  el  40m  yagi  are  insulated  from  the  boom.
Whats  the  easisest way  to  dc  grnd the eles.....  and  also  leave  the  insulator between ele  halves intact??? 
Resistor,  choke,  strap  ?

I  also  have a nema  box,  with  2 x vac relays  +  strap  coil... to  allow  for  4 x segments  of  REF.....and  also  DIR  tuning.


DE  is  not an  issue,  hairpin across  the  feedpoint.    CM  choke  1st....  then  Braid /  shield  is  bonded  to  top and  bottom  of  tower.
Another  nema box  at  DE....  but  with  2  strap  coils,  and  each  coil  tapped  with 2 x vac relays.   4  relays  in  total  for  DE.  That
provides  for   7 x DE  tuning  segments. 

I  want the  ref +  dir  dc  grounded  at  all  times.
