Preamp with twin lead wire
Date Modified: 2009-04-20

Question:
My mother won't let me run cable through her window opening, so I have to use regular twin lead wire. Can the preamp still work using a couple of cable to twin lead transfomers, at each end of the twin lead wire? I realize there will be some signal loss this way, but would the preamp still work?

Tech Tip:
Yes, you can use a couple of 75/300 ohm matching transformers to convert from coax cable to 300 ohm flat wire. The important thing is that the transformers are AC/DC power passive or the +15VDC voltage from the power supply will not reach the preamplifier.

Winegard’s model number of the matching transformer is a TV-2900.
