I have had some success with vertical monobanders on all of the birds including VO-52 and A0-7. I use a Ringo Ranger II on two meters and a 1/4 wave homebrew two meter groundplane for 70cm, which makes it 3 waves long for 70cm. The main disadvantage I run into is that two different antennas located at different locations on the house here cause dissimilar tracking of the birds.
Remember, a vertical antenna with gain will cause your angle of radiation to be lower than a simple 1/4 wave for that particular frequency. I find that with the Ringo my best angle is about 15 - 50 degrees. The 1/4 wave 2 meter used on 70 cm is a bit better. It is difficult to work AO-7 with this arrangement but is doable. Some day I'll get my arrays back in the air (down since the storms of '04').
