   Instead of 10Mohm it is better to use e.g. 0.1pF SMD capacitors as standoffs.   
      
   100pcs 0603 SMD Capacitor ±0.25pF 50V COG 9.1pF 9pF 8.2pF 8pF 6.8pF 6pF 5.6pF   
   5.1pF 5.0 4.7 4 3.3 3 2.2 2.0 1.8 1.5 1   
   0.75 0.5pF - AliExpress   
     1000 pcs for EUR 11 including shipping to   
   NL. USA may be more expensive depending on the king's mood.
