    "content": "I think I'm using the same pre-amps that you are, but a different radio \n(Yaesu FT-736).  The pre-amps are used almost exclusively on satellite.  I \ncompletely manually control the pre-amps from a box I built with controls \nfor the two pre-amps and polarity switching relays.  I have separate power \nlines to the pre-amps.\n  \n I'm with Andrew in that you should mount them at the antenna.  Mine are \nalso pretty short coax runs.  There is a photo on my website that shows the \nNEMA box with the two pre-amps mounted just below the rotors.  It's a \nlittle hard to tell that it's two pre-amps, but there really are two \nstacked one in front of the other.
