how would i check the swr's on a vhf or uhf? like for 2m? or for murs?

Same way you check it for any other band/frequency. Just make sure the meter you use is designed for the band you're checking.

well on cb there 40 channels i check it on 20 in the middle! how would i do it on vhf or uhf?

countryboy879,
It's really just the same as checking SWR anywhere. The biggy is to use a meter that is designed to work at VHF/UHF, most common meters won't do well on those higher frequencies.
Where the frequency range is fairly wide, checking at several sort of widely spaced frequencies/channels lets you know 'where' in that band your antenna shows a low SWR. The same is certainly true at VHF/UHF as well as any other 'band'. "Tuning" VHF/UHF antennas, or adjusting for a low SWR is also just like on any other band, except, you do that 'tuning' in much smaller 'chunks'! Fractions of an inch at VHF/UHF can make a big difference (antenna lengths).
And just like on any other band, once you do it a few times it becomes 'familiar' and isn't 'new' anymore... easy, sort of. Same 'bases', just a different 'ball park'.
Have fun.

so i check it in the midd le of the freq range im using

Check it at either end of the band your antenna is designed to cover and when you get it to a respectable reading then the middle should be no higher than either end of the bandwidth.

What ham bands do you currently operate on?
