Diversity DF???
ps wrote: I have a photo of an antenna at the Long Marine Labs in Santa Cruz, California. The view in the photo is to the n-n-west. I'm curious about what looks like some sort of array of rectangular elements. Is this an antenna, what type or frequency range? The length of the sides is about 1 meter. I can't post a binary on the newsgroup so the image is temporarily at this url. http://www.cyberplasm.com/temp/ant_500.jpg |

From the responses I guess this must be some sort of tracking system for marine mammal research. Whales, seals, etc. Don't know for sure. |

Probably vhf, but the clumsiest looking RDF setup I ever saw. From http://www.ucsc.edu/currents/01-02/10-08/otters.html sea otters join conservation research project at Long Marine Lab About 40 wild sea otters have been outfitted with radio transmitters and temperature monitors. |
