Improved sensitivity ADS-B receiver

With a simple dipole antenna it was easy to improve the receive results of the ADS-B receiver. I soldered two elements of about 6 cm to a coaxcable which is connected to the TVdongle. Results were great:

With DVB-T antenna; Less than 10 aircraft:

                                              DVB-T antenna (not tuned to 1090 MHz)

                                       With dipole antenna; over 30 aircraft:

Dipole with two quarter wavelength elements

Also the range is greater. I have seen aircraft near the London area
