Selective bandpass for 2m amateur radio band

This is an other purpose of a bandpassfilter. It is very simple. But to find the right lengh of cable an empiric way must be gone - and this cost time. In my case with a RG 9 B/U cable (very similar to RG 213) the lengh of the cable was 64 cm. The inseration loss of this filter is quite high but on the other hand is also quite selective.
