RTL1090 Signal Quality

[SCPD]

IF you're new to ADS-B decoding and want to try your hand at making a antenna RTL1090 has a feature called SISEX "signals in space". I use it to get a reference on how well the packets are coming in. I have provided in this post 2 visual representations of what you want and don't want in laymen''s terms. This is really meant for people who cannot have outdoor antennas because of housing covenants or living in an apartment.

My antenna I built. It is made of two 7cm stiff copper wires. I dissected a CB Firestik antenna for the copper because it's the right material for this. One 7cm length is soldered vertical to the center lead of a 1/8th inch mono plug. the other 7cm length is soldered to the long stem "ground" of the 1/8th inch mono plug. I have bent the stem outward to a 90 degree angle horizontal. This makes it a VERTICAL 'L' DIPOLE. I have soldered a female 1/8th inch female jack directly to the mcx connector of the nano rtlsdr dongle.

Please notice the two images and read the annotations in them in yellow I provided. You can work from this.

The DIY 1090mhz L Dipole

I forgot to post the image of the 1090mhz L Dipole I made that I mentioned on the original post I made.

BigBean, cool project. I'll have to download that 1090 scope program you have. At your convenience, could you post another picture with the lights or flash on? I'm wanting to improve my 1090 kHz reception. What did you use to stabilize the base of your antenna?

Its just supported by the dongle and the famale 1/8th inch mono plug. The antenna is 7 cm vertical and 7 cm horizontal. Its very very light. Direct soldered to the rtlsdr nano mcx connector.
