Hello Acars, ADS-B is line of sight, so weather conditions have very little effect.

You can see in the diagram above, I am getting around 250Nm in all directions from the propagation rings.

You should do well with that setup.  I cannot stress enough to waterproof your connections.  It makes the world of difference with your signal.  First I used a good quality electrical tape around the connections, then I covered it with "Liquid electrical tape" to make a rubberized tight seal so no water can get in.

Any ideas what NM track means
Also with the new set up would I exceed 200 miles currently in getting 159-162 on a short outdoor antenna which is on my outside window

There are so many factors that can effect your range....

Surrounding terrain, actual height of antenna.  are you mounting it to a mast, or right to the roof?  It really is a trial and error setup.

Just put it up and post the results...

Question if there is a high pressure system can that affect range like vhf

Hi Paul, as CYYZGUY says above, make sure the joints are as water-proof as possible, personally I use silicone grease, water hates it.   Get some in every joint, so as the connector is tightened it squeezes out - you know there's no-where for water to get in then.   You can find it on-line easily as electrician's silicone grease usually in 50g tubes, and you can also buy bigger pots of it from some plumbing suppliers.    Remember, we're dealing with micro waves here  frequency of 1090MHz = 27.5cms wavelength.   Purely line of sight 95% of the time, wet trees, buildings and heavy cloud reduce the signal, and unlike frequency of 27MHz = 2 metre wavelength you don't get lifts and skips.    HTH

NM is Nautical Miles (1 Nautical Mile = 1.15078 Miles)

I see your patch lead terminates in an N-type connector - you'll need an N-type to SMA adaptor to be able to connect it to your radarbox.

So is the real distance from my house the NM track or the miles so for example I'm tracking a aircraft from my house the left says 145.2 distance but the NM track says 195.0 so what I'm asking what distance is the right one
I'm asking so I'm getting a idea of range
Look forward to your reply

Hi Paul, here's an example of the silicone grease I was referring to:

http://www.ebay.co.uk/itm/1x-500g-Arctic-Silicone-Grease-Tub-Clear-Paste-50-C-200-C-Lubricant-/231391773460?pt=LH_DefaultDomain_3&hash=item35e0064314

It's also available in 50g tubes (usually Servisol and can vary in price from £3.50 up to £15 for exactly the same stuff - shop around!) and doesn't affect rubber or plastics the way that mineral oils and greases do.   A thin smear of this on car door rubbers eliminates the door sticking in frosty weather that happens if water is trapped and frozen and it works at any temperature.

Paul,

I am confused, what do you mean the left says 145.2 miles.

Hello Paul you may have found an untidy behaviour of ANRB Software:

but first: bothe distances are showing the distance in NM or if you have set te software to miles or kilometres the range in that values.

How it works:

the value in the bottom area were the MSGs/sec are shown is directly showing the distance of each airframe, which is selected on the map. But only as long as you select them on the map.

The distance in Myflight list is the distance of the airframe at the last tracked postion (complete ADS-B message received).

Now the maybe untidy behaviour of the software:
If a new airframes is selected from list (not on map), the distance value at the bottom doesn't change immediately. It changes as soon as a new position is received for the new from list selected airframe.

Hi Alan

if he means what I've understood there is an "untidy"  behaviour in the software.

I understand Ingo but they are both in nautical miles and Paul stated miles and nautical miles so I am wondering if what you have detailed is what he mentions?
