Re: Connecting 16th century antenna wire to 21st century coax



You can pick up a 300 ohm to 75 ohm matching transformer from Radio
Shack, Wal-Mart or even Walgreens for a couple of bucks. The 2 wires
from your existing flat cable connect to one side and a coax cable
connects to the other through a standard F connector.
