WebQuartz crystal filters are the optimum choice where the application requires selective narrow band filtering at HF and VHF frequencies. Because of the extremely high Q of quartz resonators, crystal filters with a fractional bandwidth of the order of 0.01% to 0.5% can be realised with low insertion loss and high selectivity. http://www.networksciences.com/pdfs/tutorial.pdf
