COIL 3.96
« on: February 18, 2021, 08:18:54 AM »

The 96th revision of my Windows coil calculator has improved accuracy for self-resonant frequency and proximity effect. Results are much more accurate for short coils. N6LF is using the program to optimize high-efficiency loops for 2200-meter receiving arrays.

COIL calculates inductance and Q for solenoids made of solid or Litz wire. It models a number of copper and aluminum alloys and form dielectrics. The program handles dielectric ribs (Air Dux) or ridges (steatite), axial or radial leads, and U.S. or metric units. COIL can automatically maximize coil Q while keeping inductance constant. It can provide results as an RLC model for wideband circuit or antenna analysis. To validate accuracy, the documentation compares calculated values with hundreds of inductance and Q measurements made with an HP 4342A Q meter on dozens of coils.

Has anybody else encountered the install issue for COIL 3.96 that I got (clip below) when I attempted to install it, and if so, is there a PC-safe (WIN10) workaround?

First thing I would do is get rid of anything Norton.  Norton's response is to do this:  https://support.norton.com/sp/en/us/home/current/solutions/v80629965

Id ask Brian as to why?

And yes, I have had no use for Norton for over 40 years or so.
