@gregy:
The simulation results for "Varying the Length of Elements" for CoCos made of:
RG6 FPE 0.83 VF;
RG58 PE 0.66 VF;
Air insulated tube;
show that the minimum SWR occurs 5 to 10 millimeters away from the length obtained by standard formula "Length = 1/2 wavelength x VF".
Please see many tables of simulations of different CoCos I have posted yesterday.
This may be due to:
EITHER
the standard formula is not precise but a close approximation only.
OR
the simulation software is not accurate & gives approximate results.
