Thanks, I had suspicions some degree of directionality and impedance change may result from "add ons". The antenna will be somewhat direction as it is already mounted
at one end of the vehicle instead of centrally mounted. So it would be uncertain as to how it may affect the pattern.

In fact this can be potentially used to advantage to a small degree, sling shot-ing the energy (and RX) a little more in one direction than another.

I would have to consider any signal report changes may relate to changes directionality
as much as globally improved field strengths.

In short I gather from the link I supplied that more ground losses = less low angle radiation. I want to think about this and experiment but the complex interactions are clearly impossible to understand without technical measurement equipment.
