You've gotten several suggestions. 6-8 Ohms is no better than 10-12
Ohms as a guess; however, just what does this program do that this
number is so important in performing what it does?


mobile.exe is a little DOS based program that gives you radiation
efficiency, Q factor, etc, after you input several proposed design
measurements of a mobile antenna. When calculating these antenna
parameters for a "fixed station" type of mounting, ( not on a vehicle, I
guess), ground loss is one figure required for input. It is NOT a
required input when figuring for mounting on a vehicle, I just realized.
