[amsat-bb] Antenna SWR question

I've been having trouble getting into the FM satellites lately. It's the same rig I've been using for a couple of years and I have not had problems before. I bought a digital meter to measure power out from the handhelds and to measure SWR on the antennas. According to the meter I'm getting 4.9 W out of the handhelds, which is expected. For SWR I've got values of 1.7 at 70 cm and 2.0 at 2 m. The antenna is an Arrow.

Are those acceptable SWR values? Should I try to get them lower? Can you even adjust the tuning on an Arrow antenna?
