FOR USERS OF "4nec2" ANTENNA SIMULATION SOFTWARE:
DOWNLOAD my two .nec files (Revised)
CoCo made with RG6 cable (0.83 VF)
Click the links below to download:
(1) Revised file: Rev-variable length CoCo 4 element FPE insulated.zip
(2) Revised file: Rev-variable length CoCo 8 element FPE insulated.zip
Files were revised due to an error (the Velocity Factor VF was entered in column for Dielectric Constant k).
How to add insulation to the core wire:

NOTE:
(1) To achieve accuracy, I have used small wire segments. This has resulted in large number of segments. Running "Calculate" takes several minutes. Running "Sweep" takes 15 min to 1/2 hr depending on your computer's processing power.
(2) Ignore geometry error message (wires 1,2,3 & 4 "too thick").
