    "content": "I have had some success with vertical monobanders on all of the birds \nincluding VO-52 and A0-7. I use a Ringo Ranger II on two meters and a \n1/4 wave homebrew two meter groundplane for 70cm, which makes it 3 waves \nlong for 70cm. The main disadvantage I run into is that two different \nantennas located at different locations on the house here cause \ndissimilar tracking of the birds.\n\nRemember, a vertical antenna with gain will cause your angle of \nradiation to be lower than a simple 1/4 wave for that particular \nfrequency. I find that with the Ringo my best angle is about 15 - 50 \ndegrees. The 1/4 wave 2 meter used on 70 cm is a bit better. It is \ndifficult to work AO-7 with this arrangement but is doable.\n\nSome day I'll get my arrays back in the air (down since the storms of '04').\n\nReid, W4UPD\nAmsat #17002\n\n\nOn 6/9/2011 12:35 PM, John Geiger wrote:\n> Has anyone had success getting into VO52 using a vertical, omnidirectional\n> antenna on the uplink.
