Theoretically then the next 2m VHF section could be added for a dual band configuration. The tuning is impacted by omitting sections as it has to do with loading and any additional length added by metal in the isolator. It might be desirable to operate at times with only one or two sections to prevent damage to the antenna where there might be trees or conditions hazardous to the antenna. This is a bit of a top heavy antenna that is not going to take much abuse from trees or excessive forces. Folding it down is fine except you cannot operate while it is folded down. Removing the top allows limited operation in the most critical bands.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.
