The antenna that comes with the SDS200 is a telescoping antenna and the SDS100 comes with a rubber duck antenna. Yes, the easily receive 155 to 159 MHz
Other than that, I am not sure what you are asking.
Why rubber duck though? Ideally you need something with a long whip to best cover VHF. Best to get something mounted outside as high as possible but if that's not an option for you, consider the BNC-W100RX. Considerably longer than the telescopic that comes with the 200. Got elbow joints too so it's fully collapsible
I'm still trying to connect your thread title to your original question. What is the problem, are you have difficulty receiving 155 MHz and 159 MHz ???
