Nice brick building. Holy smokes they put the antennas above a massive RFI source, all those AC cooling fans. Geesh. They do get some weather protection under the eaves. The large antenna is pointed almost parallel to the ground, likely to a mountain antenna, for a shorter, faster path to the cloud compared to geosync orbit. The small antenna appears to be pointed skywards? Or way higher up on the nearby mountain? Could be both are going to nearby tall pole? That metal sheet roof does not look like it would take kindly to antennas. Multipath reflected waves? Can one mount wifi on metal roofs? What vertical distance above them must they be? Guess I am talking only omni. The large antenna's lead can not be seen, and it's bleached appearance leads me to assume it is the first, older antenna, either no longer used, or for some other reason than wifi. It's larger size states to me more bandwidth, weaker signal, older electronics, etc. The small antenna has a lead showing just below it, leading around the corner, behind the brick access wall. There is that black post at the end of the access wall. Looks like either a weather proof box for an omni antenna, or a vent pipe for the sewer, more likely not a wifi antenna as then it would have to punch through the building for wifi over there (or a second antenna). Then there is the antenna on the roof. Very specialized type. It does not look like a wifi antenna. Nor TV. More like a loaded, highly directional, high gain for CB, given the width of the antenna placing it in the TV channels 4-5 range. I've never seen a two story rest stop, and I see an open window up there, so some type of office space with daily staff, which needs the CB like antenna. Likely it is for radio band monitoring for highway patrol channels, or DOT channels, or both. Cool pic Dave. I got a lot from it. I can see government is finally spending 'good' bucks on wireless at remote locations. I like that. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "SOCALWUG" group.
