This does however, slightly narrow the bandwidth of the antenna if the coax loss is small because as you move away from the perfect 1/2 wave point the coax will start to show SWR. For monobanders this usually isn't a problem, but it may be for some tribanders.
This will also work on all the non-WARC bands. For Tribanders, if you cut the coax for 1/2 wave on 20 or 40 meters, make sure you tweak it for multiple of 10 meters, which will be a more critical measurement. The rest of the in-between bands should fall into place. >>> You can easily make the 75 ohm coax essentially "invisible" in a monoband application by using some RG-11 to extend the total length of the 75 ohm feedline to any multiple of 1/2 wavelength.
