Theoretically then the next 2m VHF section could be added for a dual band configuration. The next 2m VHF section could be added for a dual band configuration. When experimenting like this NEVER transmit unless you carefully check your SWR on your transmitter low power setting. You can easily fry your mobile rig messing around with the antenna.In the two section dual band configuration the 70cm resonance tend to go back to a lower frequency better suited for ham operation rather than GMRS operation. This is desirable for true dual band ham use. The VHF side then becomes the portion of antenna slightly too short for optimal resonance on 2m ham. This can be corrected by a simple lengthening of the second, or in this case, top segment. The correct length can be obtained within the distance permitted and with the setscrew tightened the antenna is correctly tuned for true dual band 2m / 70cm ham operation.
