209-1: The 5RadU Operations site has been
circled in red to show its position relative to the airport. To the left
of the green dot is the Operations Building. |

209-2: This closeup reveals an antenna
field just north of the Operations Building and another to the north west.
The time of day and the altitude from which the photo is taken makes it
very difficult to discern most of the antenna masts. |

2007: This is the same area of image 209-2
but as a satellite photo in 2007. |

209-3: This is how the three rhombic antennas
were positioned in the antenna field NW of the Ops Building. The antenna
on the right points approximately north while the middle and left antennas
point approximately NW. The left and middle antennas are offset by about
20 degrees from the right one. To obtain this rendering, it was necessary
to scan the area of interest at 600 dpi, then convert the image to
a negative. In this state, a few of the masts were barely visible. Using
experience and prediction, the 3 rhombics were rendered in the positions
seen here. |

209-4: The antenna field to the north
of the Operations Building. In spite of attempting 1200 dpi scans and varying
contrast levels, it is impossible to see any antenna masts due to the lighting
conditions in the original photo. |
