Hi George,
Arrows are great antennas -- when I first put up my az/el system in the backyard I used an Arrow 4-element 2-meter yagi for the uplink, and it worked just fine. One thing I noticed was that after a month in the elements / rain, the studs connecting the aluminum elements together had corroded pretty severely -- I think the aluminum didn't like all the rain, and I could barely get the elements apart. I've seen some reports of other hams using arrows fixed on rotors in dry environments (Arizona), but if you're going to leave them outside in the rain, you might need to take precautions to prevent corrosion of the element connectors.
