Title: I have 2 questions about the RB
Post by: Jordan on May 02, 2009, 04:23:42 PM

i was wondering, the 250 miles range, is with the supplied antenna?
also, whats the connection of the antenna (got the grammer wrong..)? BNC or SMA?
for the first question, im on an 8th floor if the height helps.

Hello,
250nm is the 'maximum' range of the ADSB signals not the range of the aerial and the connector is a SMA. Hope that helps.
 you could look at some of the polar diagrams here to see the range for the RB aerial.

Hi Jordan,

Here are details of how the antenna is connected to the box:

http://www.airnavsystems.com/forum/index.php?topic=634.0

The 250 mile range is the theoretical maximum and you could see aircraft out to this range using the standard antenna if it was out in the clear with nothing between it and the aircraft.  However, if anything gets between the antenna and the aircraft, then the range will be less.  If you can get your antenna on the roof of your tower bock, your reception should be good, but if it is on a window ledge, then the building will shield some aircraft.

Of course, this doesn't matter too much if you use the Network, as you can then see aircraft worldwide wherever there is a RadarBox user sharing data :-)

Ok thanks, generally I receive aircarft (ACARS and the normal voice freqs) on a good day as far as 250-300 miles away and radar stations 400 miles away.
I have an external antenna that is about 90cm long, but im wondering if ill have the same great recepection with the supplied antenna, because i want that the normal antenna i use will remain for listening

It's almost impossible to tell what your reception will be like until you actually try.  Where about in the world are you?  We might be able to upload a screen shot so that you can get an idea of what you might see.

Im at the middle east (medeteraninan area not the gulf)

Jordan,

Here is a quick shot of the whole of the Mediterranean. The aircraft just appear as dots as I've zoomed out a long way.  Red is descending, blue is climbing and green is level.

Here is the eastern Mediterranean zoomed in so you can see some detail.  As I'm in the UK, this is all RadarBox Network traffic.

And one last shot centred on Kuwait.

The antenna for ANRB will display different reception charecteristics to the one you use for voice/ACARS transmissions.

Voice/Acars  is  in the range 108-136Mhz (VHf- civil) or 225/400mhz(UHF- Military).
The VHF antenna will not work with ANRB - you have to use the supplied antenna (or suitable other  - for the frquency)

ANRB (ModeS transmissions  ) is at 1090Mhz and will in general be more prone to attenuation than VHF.....more easily blocked by high ground/buildings etc etc.

My antenna is a general 25-1300MHz antenna.
the buildings and hills are no real factor for me...
Allocator thanks a lot for the images.

You will tend to get better reception using a dedicated antenna rather than a  multiband one.

Ok, I have another question about the network feature.
What i will see is the traffic from other receivers (of otehr users like me) through out the world? or receivers of the company?
and is there a receiver around the Munich/Frankfurt area's?

Yes you will see other users data which they have picked up. Almost all of Europe is covered so there will be plenty to see :)

Great thanks, any chance someone can upload a photo of the EDDM area?

Title: Re: I have 2 questions about the RB

It's a bit quiet at EDDM, but it's busy all around!

Just saw BAW109 on the Heathrowcam Radar site and already in that area..
cant wait untill ill be in London and ill buy this thing, im already a huge fan of the airband, only to think what ill do with this baby..
BTW does it look like that when u zoom out on the network feature, if youll zoom a lot closer will it show Nav aids and airport and such?
sorry for all of the questions, but i gotta check something real good befor ei spend 400 pounds on it

You see much more detail as you zoom in and you can choose what you show.  Almost everything is turned on here, but I don't usually have all this on.  Very quiet at London Heathrow at this time in the evening.

Jordan,

You should down load the RB software and give it the demo test drive.

Title: Re: I have 2 questions about the RB
Post by: Jordan on May 04, 2009, 11:45:33 AM

Which one is it, there are a lot of softwares on the download are...

Title: Re: I have 2 questions about the RB
Post by: Allocator on May 04, 2009, 12:05:39 PM

The software is on this page, it is the full version of the software, but it will only run in demo mode without the RadarBox hardware (receiver) plugged in.

And this is the direct link to the software:

Ok started it up and everything, but i cant see a map, im receiving a lot (wish i had that amound here, on ACARS i have 68 flights since 2 hours ago) of aircraft but i cant see the map

Go into File -> Preferences -> Map -> Import and select Real Radar

Then click OK, and OK to close the Preferences menu and the map should appear.
