Good morning what sort of ranges do you get from your radar box
I know it depends on your aieral
Also is the 1090 freq work like vhf with lift condtions for extra range
Look forward to your repiles
I would be interested from members to send me there ranges
Paul
Using the supplied antenna mounted externally (I know!) at sea level, I get about 100km.
Using a roof mounted antenna at about 110 ft ASL I get 160-180 nautical miles as standard - though not completely round 360 degrees. There are a few black holes.
There does seem to be lift on occasions in high pressure, and then my range can exceed 200nm.
Altitude of the aircraft is the big factor and the 40000 ft high flyers will extend your polar diagram boundaries.
Paul,
I get up to 220nm with a DPD antenna on the roof.
Andrew
With standard supplied antenna, mounted externally (but weather/water-proofed) at around 200' asl, I get consistent 220nm with A/C at FL350 or more.
400 Nm + with my setup. DPD Antenna
regards,
Hi CYYZGUY,
Do you have a screenshot of your Maximum Range Polar Diagram?
Andrew
Hi Andrew, let me try to get a fresh screenshot for you tonight when I get home from work. (It's only 10AM here toronto time) My polar diagram/mode S rings has changed quite a bit since I took my screenshots months ago.
You probably wont see it until tomorrow your time...
Hi guys thank you for the info
I run at outdoor aieral with slim jim pre amp I get about 180 miles if I get a roof top aieral will the range in crease
Paul
Hi Paul, the thing with pre-amps is that they need to be installed as close to the antenna as possible...Also, cable length plays a huge part in your overall results as well. The longer the cable run, the fewer the results...Now, it also depends on the quality of cable. I am using LMR400 which is considered to be "very good", is still somewhat flexible, and can accomodate a PL-259 connector perfectly. I wanted to use LMR600 cable, but it starts getting very stiff and hard to work with. A good quality cable, kept as short as possible will yield the best results...
I get such good results because I have a huge height advantage compared to most people.
Jason
What height ASL are you Jason? Paul, a pre-amp will not increase coverage, it may even cause less contacts. A pre-amp is only good for overcoming long co-ax runs, If the antenna isn't receiving a signal, a pre-amp isn't going to create it! Height and clear horizon are the most important factors.
Thqnk you so much for info paul
Hi Jon, The City of Toronto and surrounding area is about 76 meters above sea level...
http://www.toronto.ca/toronto_facts/geography.htm
However, as you may or may not know, I have my antenna mounted on top of my apartment building, it is up about 35 meters from the ground itself. Pics are in the sticky thread "Installation Photos"
Jason
When do you think the radar box alerts will come back
Hi Jason, your height ASL is around 350 feet, so your range is remarkable. Can you post some screen shots with rings please?
Hi John, here is the screenshot with rings.
Unfortunately I had to zoom out quite far to fit the rings into the screen as they go out quite far from my home location. My range encompasses 3 of the Great Lakes completely. Remember, I have my antenna mounted at the top of my apartment with absolutely no obstructions in sight and I am well above any trees or any kind of blockage.
regards,

Hi Paulfineman ... it would be a very simple solution if AN would agree in let everyone to send emails directly with our own provider servers.... But AN for some reason wont not to do this way... so, be patient.
Cheers - juan
On the radar box ranges who has had best range
Can you send examples
Paul
Paul, what kind of range are you getting???
I don't think any other airnav user out there has the consistent range that I get of 400+Nm
Jason
Hi Jason,
Your screenshot shows the Mode-S Signal Maximum Range.
It would be very interesting to see your screenshot with the Maximum Range Polar Diagram as well.
Could you also show the Dist(NM) field as well. If you click on the field name it will sort the aircraft by distance.
Thanks a lot.
Andrew
Ok, will enable those features once I get home...again, it's 13:00 hours here toronto time so you will see it tomorrow some time.
Cheers,
Has anyone got uk maps showing ranges
Paul
Here's my range centered just North of EPGD - circa 175 miles.
Here`s one for you.
Dave.
I am 16 miles north of EGAA.
screenshot from today.
homemade antenna , H1000 coax cable, 18 meter above sealevel.
some small hills (65m high) SW,S and E of me.
and the antenna
2200 hrs tonight.
John
Thank you very much for your maps
Showing ranges etc
Paul in kent

Hi Bratters,
Congratulations for your homebrew antenna !
Congratulations for you achieved range !!!
Congratulation for your excellent screen-shot !
Very seldom someone takes a screen-shot of Polar diagram including the Max Rings ....
Likely thinking that everyone in the world knows very well the area he lives .....
since ... "my place" is the most important place of the whole world .... sure 8 billion people
knows about it !!!!! And everyone knows how many NM i am receiving ADS-B signals !
RDSSSSSSSSSS
Cheers, Best regards - Juan
Late, but here is my range too...
Regards
Ingo
Thanks for the kind words Juan - that screen is my normal working set up.
One small correction - it's not a home brew. I bought the antenna from a local shop (about 50 euros) and put it on the roof. I used the shortest possible aerial cable into the loft where the box is kept then a very long USB down into the house and the PC.
I'm pleased with the range. particularly as I am very close to sea level in altitude and smack in the middle of the country, but that polar diagram is the product of two years tracking!!
Hi , I am using a homemade collinear from here http://tech-software.net/1090_ant_02.JPG (http://tech-software.net/1090_ant_02.JPG)
It is connected to radarbox with 10 mtrs of heliax. I am elevated about 180 mtrs asl and 1 km from the water. With this I can receive over 300nm ( 500km ) towards the Australian mainland
Mike
Hi guys, here's mine, with a totally bog-standard supplied antenna that I've waterproofed and mounted outside - height approx 215' asl, the sea being approx 100 yds to my west. The severe cut off to the east is due to our roof's gable ridge, which hopefully be overcome when we alter our roof - if Planning permits. The cut out in the sw is due to the prescence of a building - the Mullion Cove Hotel! Again I'll hopefully be able to "see" over the top to the true horizon, when I can mount a Diamond Radar Extender and an SSE 1090SJ outside and 10 - 12 feet higher.
