I think you could do better by simply installing the PR6 at the K3 and using low loss coax to the antenna. Almost all the 6m EME stations around the world use a good external preamp in the shack. If your coax cable loss is 1 dB or less, you will not gain anything by mounting the 6m preamp at the antenna. You can model this for yourself in the EME CALCULATOR (accessed from the EME ECHO MODE screen in the old WSJT Version 4). Because the EME CALCULATOR and EME ECHO MODE were never re-written in the language used in more recent revisions of WSTJ, that old version is still available: http://www.physics.princeton.edu/pulsar/K1JT/WSJT498.EXE I think you will find it much simpler to keep the preamp in the shack!
