      @bruton:
      This looks great. You have crossed the 9th (outermost) ring at many places. What is the gap between rings/ how far is the outermost ring from receiver?

      I have set 6 rings 50 Nautical Miles apart, so my outermost ring is 300 Nautical Miles from receiver.
      (300 Nautical Miles = 345 Miles = 555 Kilometre**)

      **In UK English, Canadian English, and French, the spelling is "kilometre". In US English, German, Swedish & Dutch, the spelling is "kilometer".

          @bruton:
          Your outermost ring is 9 x 20 = 180 nm. Your max range is somewhat beyond outer ring, so it can be safely taken as 200 nm = 230 miles = 370 km. Very good for an antenna in loft.

          You will see considerable improvement when you take your antenna outdoor on your roof or a mast.

          Adding an amplifier will greatly enhance range & number of planes, both for antenna in loft and antenna on roof.

            Looks great! what great coverage, can you confirm where you got the information to build this as would love to do the same.

                  Adding a Sattelite Amplifier will increase range greately.

                        Ive ordered one and an in line amplifier to see how it goes.

                          (1) Which amplifier you have ordered? There is a huge veriaty of satellite amplifiers available, but all are not good. I have discarded 2 satellite amplifiers + 1 tv drop amplifier before finally succeeding with RCA D903. This does not mean your first one will be crap. It depends on luck.

                          (2) Connection to the inserter in picture in my above post has to be done this way:
                          HF goes to DVB-T
                          HF+DC goes to Amplifier's "OUT" or "TV" terminal
                          IN goes to ac/dc adapter's dc terminals.

                          (3) Connection at Amplifier have to be done this way:
                          Amplifier's "IN" or "ANT" terminal goes to Antenna
                          Amplifier's "OUT" or "TV" terminal goes to DC inserter.
