This is my quick and dirty shoebox feeder, made out of a (horribly inexpensive ) recycled fruit crate:

Great, congratulations!
It does not matter how it looks, as long as it performs good. Any way it is good looking as well.

- test antenna on the top (antenna that was delivered with the stick, shortened to 6,5cm)

Is 6,5cm length of removable part?

[Receiver] Not a beauty, but (almost) a BEAST!

This is my quick and dirty shoebox feeder, made out of a (horribly inexpensive ) recycled fruit crate:

- Raspi B+
- Powered USB - Hub
- WiFi connection
- 5V supply with ferrite core filter
- test antenna on the top (antenna that was delivered with the stick, shortened to 6,5cm)
- productive antenna under the roof
- Aircraft noise feed to

DFLD feeder
XRDP remote access

On my Windows Workstation:
Remote Desktop to the Raspi

My Default Setup
Photo shows antenna (Cantenna) only.
Not shown in photo are the DVB-T dongle & Raspberry Pi, which are on the floor below the antenna.
Cantenna >> 12 ft / 4 m RG6 Coax >> 6 inch / 15 cm RG174 pigtail F to MCX >> DVB-T Dongle directly plugged-in into Ras Pi >> Ras PI >> 15 ft / 5 m Ethernet cable to Router

My Mobile Setup

(1) Choping-off whip to a length resonant at 1090 Mhz greately improves max range / plane count. Please see sketch below.

(2) Placing the mag-mount base over a metallic surface (sheet/can/window sill (if metallic)/car roof) provides a better groundplane and further improves performance.

Ok, thanks for that! Your last link is most interesting .

Thats because I hit delete instead of move incorrectly.

However:

This thread is intended to help newcomers and those starting out with aircraft tracking to get a feel of what DIY hardware modifications or additions can be used outside the usual basic kit items to extend or improve range.

Please ask posters questions about their setup or for help in replicating some of these in the other thread here http://forum.flightradar24.com/threa...cussion-Thread

Coverage is good but it can be better

We don't have issues with lightning here but it's an item on my list

Hope I didn't offend anyone with that caution about an antenna's potential probability to by struck by lightning (i.e. this thread has been heavily censored) . But it is something that is known and has a probability of occurring depending on location. All antennas that are elevated above other surrounding structures need to have lightening protection.

Nice setup and looks like amazing coverage. Have you considered lightening strikes? You should have a good path to ground with the top aluminum section just in case. Also, you might want to use something more substantial than the plastic cable ties in case of a lightening hit.
BTW, what is your altitude above sea level?

Coverage is good but it can be better

We don't have issues with lightning here but it's an item on my list for the new construction to investigate. For the new setup I will have all the equipment housed inside an enclosure that is attached to the pole. From the house I wil run a cable for power and an Ethernet cable.

The FR24 GPS that is about 3 meters above the ground shows a reading of -24.8m AMSL
According to Google Earth the elevation is 7 m

Don't you were told that no man should serve two masters?! What to say about three?!

Don't you mean one of the gaps is to northwest?

The Fr24 antenna is pretty high and you want all of them higher. Don't you have problems with winds and lightining strikes?

LOL, there will be a position for a 4th :P

Correct, it's NW and not NE. Changed that.

Winds will be a problem. The aluminium pipe is smaller in diameter and thus flexibel. When the winds are strong it swings (mainly due to the cables that run to the house) and that's why I plan to attach guy wires.

Actually, the most curious gap is directly to the south inline with the airport. What is going on with that?

The gap to the south is a result of the flight paths combined with my maximum range. As I stated there is east-west traffic over the southern part of the country.
In may of last year there were 3 aircraft flying all over the country for meteorological research so I hope they'll return this year.
