Hi Bjarne,
to "shunt it" means that now even DC can pass. Too dangerous in my opinion.
Checking values from 1nF to 200nF showed, that replacing the original 330pF cap with
C0G/NP0 SMD (value 100nF to 200nF) will bring a remarkable signal improvement from VLF
to the 60m shortwave band. After eight days of dxing i have not noticed any negative
"side effects".
(Btw: the value 4,5nF that was in discussion weeks ago is too low for longwave and VLF) 
 This is how it looks like in my HF+ (one 100nF + two 10nF in parallel = 120nF)
