I am told that many of the satellite transmission signals are weak and an antenna mounted preamp provides a significantly improved signal. Thus, I purchased a 70cm Landwehr preamp from Radio Dan in Los Angeles, CA. It is a refurbished unit, from Landwehr so I do not have an original instruction booklet. I received a one page photocopy of some specs and wiring diagram.
Does anyone know if the preamp can be installed without connecting power to the remote port? From what I can tell, the unit is self switching on trasmit up to 150W. Since I will only be using a 50W radio, I want to know if I still need to run 12v to the preamps remote port. It seems like the remote cable is only needed if transmitting above 150W. Is this correct? Also, is this a unit that either works or doesn't work? Since it is a factory refurbished unit, I would like to know it is operating properly.
Can anyone provide assistance?
