    For those who are keen to be displayed-feeder, and cannot get equipment from tracking site, your proposal is a good solution.

    However since I am not keen to be displayed as feeder, nor keen to feed data, I will not spend 650 eqv $1000 on feed-specific receiver. I would rather spent this money in purchasing test equipment like oscilloscope, signal generator, antena analyser etc etc, or spent it to help some one.

      The specs show that it is a very good & professional antenna. It is worh investing for those who want a professional system.

      As far as I am concerned, I am not willing to burn couple of $100 bills for it, as I can find better uses of this money. I prefer to design & built antennas myself.

        I'd like one too, preferably not at my expense.

          You have to wait till Chinese start manufacturing these. Then you will be able to get it at current European/North American price divided by ten

            That antenna probably costs 2 grand.... it's got FAA certification, and anything that has strict government and military specs is always pricey. But at the same time you want to be assured it's going to work in all situations when it's being used by ATC.

                For Military, country's freedom & lives of it's ciizen are at stake. For Air Trafic Control, lives of passengers & crew are on stake. They therefore go for the most stringent specs to get best perforamce and Maximum Reliability even in the worst condiions. To meet these requiremens, the cost shoots up exponentially. But looking at the stakes, the obvious choice is to pay that price.

                For hobbyists, nothing is at stake, and it is illogical to pay such a high price, except when the hobbyist has won first prize of a lottery or has hit a jackpot in a casino :-)

                    I don't think the wax-whip antennas on the table would be very effective.

                        • HOW TO MAKE A POWER INSERTER
                          USING A TV CABLE SPLITTER, AN INDUCTOR & A CAPACITOR


                          Step 1 of 4 - Obtain an ordinary 2-Way TV/Cable Splitter
                          Do NOT waste your money on good quality costly Splitter,
                          as you are going to use only the housing of the Splitter.
                          Purchase the cheapest one you can find.
                          The good quality costly ones have component mounted on a printed board inside,
                          which you will throw away.

                          Step 2 of 4 - Remove the back cover of Splitter

                              If you do not have an electronics parts shop nearby, you can order Splitter, Capacitor & Inductor on Line very cheap, but will have to wait 1 to 2 months due to surface/sea shipping from China:
