The SDS-200 will improve performance, but not reception. Only an antenna will do that. I had to switch to a Yagi to clean up reception on an SDS-200 and a BCD536HP. Neither did very well with the discone.
AND, of course, the higher the antenna, AND the better the coax, the more likely it will work for you. LMR 200, or even 400, if you can handle it.
