Those VSWRs are good and should cause you no trouble.

Every antenna has a single frequency or a small frequency range where it operates at its best. Small being one or two 'channels'.

For all regions of radio frequency on either side and the farther away the efficiency drops off. Sometimes slowly. Sometimes very fast. The difference in radio range from ch 1 to ch 40 is pretty great. So only a .5 to a .7 at the extremes is a good antenna match for such a spectrum.

did you add a 8 foot peice of coax and check again if it still reads 1:1 you get 4**** for antenna matching!
