I would agree, normally, but I have sold many ground kits here for $3-$5 
each (new). And have seen many for sale on ePay an other places for low 
and close to these prices.  I am not trying to sell any here and now.  
Please do not ask if I have any "???" for sale ... I will not reply too 
those.

Bottom line ... the grounding of the Heliax should be done per Mfg's 
recommendation ... they have more experience than we do ( I hope) and I 
do believe there are certain NEC codes that are applicable to this.

Look around you will find complete new ground kits ( with sealants, etc)
