If the radios are covered by FCC Part 15 (like I think they are), then there are specific limitations on the length of a driven element (one meter IIRC), and the input power level into the final stage of the amplifier (100 mW, agian, IIRC).

As I recall from reading the regulation a long time ago, the length of the active element is from the last circuit component to the tip of the radial.
