Bingo.


The problems with applying said theory in a mobile environment, are:

  1. The radio is rarely directly connected to ground, making the connection to ground longer than the physical length of the coax as it has to travel up an additional wire.
  2. The velocity factor of the outside of the coax is unknown unless you have measured it, and is almost certainly different than the velocity factor listed for the inside of the coax, generally higher.
  3. In addition to the above, the interaction between the metal body of the vehicle and the outside of the coax shielding will also affect the physical length of coax needed.

Is is possible that their is someone out their that can account for these issues?  Sure, but I wouldn't waste my time with something like this when other methods are much easier and generally more reliable.
