In theory, that would require lengthening the elements and changing the element spacing. Simple calculations will show that the actual dimensions involved would be very small. Since the OP proposes to use it in a receive-only situation, it might be interesting to just find out how it will do in its current condition by hooking it up, pointing it toward a known site, and locking the scanner on a known control channel to see if it detects a signal.
Nothing ventured, nothing gained...
