I have always wondered if the receivers and transmitters were installed together on the CAB…or if they must be separated ?
I used to “feed” the North and South Tower ATC for LiveAtc.net at LAX, and have a clear view of the CAB from my roof top antenna. I get excellent reception for ATC and A/C transmissions, tower, ground and approach/departure.
But this has always bugged me.
It would seem that if together, they might cause some interference. If that is true, does anyone know the actual location on the field of LAX, where the transmitters( or receivers) are located? Would they be close to the ILS equipment? or again would that be problematic?
Or possibly installed near the radar installation? I know where that is located, which is just north of the 24’s.
Just an ATC enthusiast and amateur photographer who is curious of the answer. Although my J-Pole antenna has line of site to the CAB…It doesn’t make sense that the transmitters and receivers would be together. Wouldn’t they cause interference??
And since I do not have “line of site” to any other portion of the airport, why is it that the reception is so good ?
I apologize if this sort of information is taboo here. The question has been asked by many around the internet. If you know that it is something classified, then say so. If not, then why the paranoid answer?
He was just making a “funny”. I don’t think the answer is classified. It’s also highly doubtful thought our Muslim “friends” would post such a question in preparation for their friendly destruction of our country.
Some of the antennas may be on top of the tower, but most likely the FAA has a couple of antenna sites around the airport for better coverage. ( check around the radar antennas…the FAA transmitter sites are easily distinguishable designs).
The antenna site for the Long Beach airport is over next to the UPS ramp near Lakewood Blvd.
Thanks. I’ll look more closely next time I drive down Westchester Pkwy. There are rotating radar dish’s there, between the pkwy and lincoln blvd. ( actually they used to be right next to the 14th hole at the gold course, before they reconfigured the roads.
But now I see I’m not wrong about thinking the transmitters would be remotely installed from the cab.
There is no reason for the antenna farm(s) to be near an airport. However, Los Angeles TRACON was near Nash and the 105 until the mid 80’s inside an old and very run down hangar.
Very nice picture of what the antennas look like, Mr. Holbert.
They either are what you described ( center radios) or they could also be the remote outlets for Flight Service in that area. Or, they could be doing duty as all three.
The “old and very run down hangar” was a neat building. (Yes, it was old and run down.) The old LA Tracon was in the center of the FAA side of the hangar, inside what was essentially a large portable building. Upstairs on one side of the hangar were the Tracon admin offices, conference room, training rooms, etc. On the other side of the top floor was the old Los Angeles Flight Service facility. The LA FSDO had an office in the hangar, also.
It was an interesting place to work. The FAA used it for deliveries for all sorts of equipment, so the hangar floor was perpetually filled with crates and pallets full of stuff.
The next section of the hangar had the Northrup corporate fleet, and the last section of the hangar was the Coast Guard’s.
Up on the very top floor was a roof access panel that I used to get on the roof catwalk. It went all the way across the hangar, and you could sit up there on the edge of the hangar and look out across the airport.
Well I found a few possible sites around the airport. Don’t really know what the set up would look like, but interesting none the less.
As I said before, I was more interested in the interference that might be had, if they were in close proximity.
Here is one I found on Google Maps. It’s north of the airport, between Lincoln and Westchester pkwy. That area used to be right next to the 14th hole at westchester golf course, before they put in the pkwy.
And another. This site is located in an area where me and my buddies used to play when I was a kid.( early to mid 1970’s) Now it’s part of the endangered Blue Butterfly Habitat. I didn’t know there was anything installed up there. A VOR site?
Would that be the newly installed ground detection radar system?
From my atc feed, I have heard tower control many times say that their alarms were set off, usually when an a/c encroached too close to another a/c during takeoff or taxi across active runway.
I don’t know how the runway proximity alarms work…but ,I don’t think it would be linked specifically to the ASDE, because the ASDE works with the aircraft’s transponders, not raw radar targets.
edit: Well, that might not be right…the AMASS system uses the ASDE…I’ll dig around some more…
edit 2: This article says its “radar connected to status lights”:
