    By the way: just for fun I made a J-Pole TV antenna for use with DVB-T tuned to 625MHz.

    It worked MUCH better than my amplified Terratec indoor antenna that I used to use previously.

      I have this as my set up but see a huge reduction in traffic, any ideas?

        @EGGD11

        When I purchased my first amplifier, its frequency range was 47 Mhz to 2500 Mhz and performance dropped drastically.

        I then purchased another amplifier whose frequency range was 950 Mhz to 2050 Mhz, and it greately boosted the performance.

        The reason is that the tv vhf & uhf bands, fm and many cell phone channels exist in the frequency range 47 Mhz to 950 Mhz. The first amplifier amplified all these signals and fed to input of dvb-t dongle, severely overloading and saturating it, causing drop in performance.

        The second amplifier's lower end frequency is 950 Mhz, so it did not amplify tv, fm and cell phone signals, hence did not overload dvb-t.

        I am using the 950Mhz - 2050 Mhz amplifier (actually meant for satellite K-band) since 2013, and very satisfied with its performance.

          Hi jmcq & ab cd,

          I've been making progress with my setup and I can confirm that the amplifier above suggested by ab cd works. I've tried 2 amplifiers which cover the frequency 47 - 2400 Mhz and they don't work in this scenario. They are however, fine for boosting a satellite signal. I bought one which covers 950 - 2300Mhz and that works fine. http://www.ebay.co.uk/itm/Satellite-...item51a4d4b5b1
          Maybe someone can explain why?

            Thanks I knew you would have the answer. I will purchase one of these https://www.ebay.co.uk/itm/370261093737 and I'll give it a try, that's after I purchase a new RPI2 as mine decided to fry its self tonight.

              my rank is getting worse. It is saying my up time is getting lower and lower but it is up 7 days a week and restarts on 7th day

                ok just checked tonight and my world rank is 1285 and my UK rank is 93. Im happy with that rank for an indoor antennae.

                  Great! Congratulations.
                  Try different locations indoors to find the best. People have reported attic and large window in uppermost story of the house to get better results.
