Er, just replacing an antenna will not make call quality better.
Comms between your phone and the antenna are digital whether calls or data.
As long as the data is getting through then the call quality will be the same regardless of whether the antennas are really old or even half rusted out and hanging off the mast as long as they are connected.
The better quality will be either 2G coding going from half rate to full rate (although I thought Vodafone did full rate everywhere now anyway) or the introduction of HD voice over 3G. HD voice though as has been said will only work to another 3G connected Vodafone handset.
Better quality antenna will only affect coverage range and data speed, not call quality since the maximum bit rate for a full rate HD voice call is about 24Kbps.
