So the Argtek has served one important function for my Phantom. That is... it has enabled me to install an Alfa APA-M25 5.8ghz 10db flat panel antenna on my remote. The original argtek blue proton range extender kit was plagued by poor quality 5.8ghz antennas. However it is still completley salvageable. If you are like me and have discovered the range of this kit insufficient even though it was properly installed... There is hope. What worked for me was installing an Alfa APA-M25 5.8ghz 10db flat panel antenna on the middle terminal of the argtek base and a pair of the smaller Alfa 2.4ghz 7db RP-SMA antennas on the outer two. These can be ordered from Amazon for a total of 40 dollars and shipped very quickly. You will then be a member of the mile away club.
