  • Thanks guys.Tried to install my FA antenna as far as possible but the length of cable was a major constraint.

      Are these on the same frequency ?

        Yup! Both are 1090 MHz ADS-B antennas.

        • So why not use just the one antenna ???? or receiver for that matter ?

          • Because contractually one is not allowed to feed a provider (FlightAware) with data from another providers equipment (FlightRadar24).

              Using one antenna or receiver is against the T&C of the agreement.

                  Flightradar don't allow you to feed data from their equipment to rival tracking services, this is very reasonable in my view as they own the hardware.
                  If you want to feed flightaware or PlanePlotter then you have to provide your own equipment, if you have your own hardware then you can use one reciever and antenna to feed as many tracking sites as you like (including FlightRadar24) but then you would only be a 'T' feeder not an 'F'.
                  I cannot answer the separation question, however an easy test would be to install them progressively closer and see when the range starts to drop off, then post the results for us all to know.

                  • Greetings everyone,
                    My question is, has anyone had any beneficial results from using a "Signal Booster" or "Amplifier" of some description?

                    If yes, what make / model has been used and where was it purchased from?

                    Regards and thanks in advance,
                    Nigel

                        Stock antenna's supplied by FlightAware (6dBi) and FlightRadar24 (5dBi).

                          l
                          Yes but,
                          I use:
                          Axing SZU 19-00 950 MHz High Pass Filter - Ebay from UK.
                          followed by a satellite TV amplifier - cheap from ebay.

                          The Sat TV amp has DC passthrough so I dismantled it and removed the inductors from the input and output.
                          The required 12V is then supplied directly to the preamp rather than via the coax.

                          The amplifier alone increased the signals but I then had severe interference from local strong transmitters on other frequencies.
                          The high pass filter stopped the interference.

                          Ideally the preamp should be before any losses such as coax cable and filters, but in my case, I need the filter before the preamp.

                          The cheap preamp is worth a try at the price....

                          Edit:

                          My location is high above Bass Strait with a clear view over the water. Without the preamp, I was receiving some signals from 250nm+
                          With the preamp, the number of reports from 200nm and beyond increased significantly.
                          It made little difference to the close signals.

                          If you don't have a good view now, a preamp is unlikely to help.

                          • I have replaced the plastic pole with a steel one but the number of positions reported have dropped even though this pole is 2 ft. longer than the previous one.Is it because of static build up or there is some other explanation?

                              Did you electrically isolate the antenna from the pole ? My guess is that the added metal has distorted the radiation pattern... or maybe its Sunday and theres less traffic ? lol

                                Does it mean using an insulator like electrical tape to isolate the antenna clamp and the steel pole.
