Double Wire Loops

by Neil Bauman, Ph.D.

A lady asked:

Why would I want a double wire loop for my induction system? I don’t understand. What is the benefit?

You don’t need to make a double wire loop if you don’t want to. A single wire loop works just fine if that is the wire you already have. The advantages of a double wire loop are:

  1. It makes a stronger signal. This may not be all that important for a small loop, but if you are running the maximum sized loop for the power output of your loop amplifier, the extra signal strength certainly helps give a better signal.
  2. Because the electrical path in a double wire loop is twice as long as in a single wire loop, it has twice the resistance in the wire. This is a good thing because it helps the loop amplifier to run cooler since the signal is dissipated in the wire–not in the amplifier.
  3. I typically buy standard “lamp cord” for my loops. Since lamp cord has two parallel wires, it is a waste not to use both wires when you can do so very easily. (Note–Never use both wires by twisting the wires at each end together. This creates a parallel circuit and reduces the resistance. This is a bad thing.) Click here to learn how to hook up a double wire loop properly.
  4. It is very important to have the proper resistance in your wire loop if you are using a standard PA amplifier (voltage amplifier). These amplifiers require adequate resistance (technically impedance) or the current will increase and burn out your amplifier. This is not a problem with proper loop amplifiers (current amplifiers) such as the Univox2A. You can read about these wonderful devices in my article, “Loop Systems–The Best Kept Secret In Town!“

"The wages of sin is death, but the gift of God is eternal life [which also includes perfect hearing] through Jesus Christ our Lord." [Romans 6:23]

"But know this, in the last days perilous times will come" [2 Timothy 3:1]. "For there will be famines, pestilences, and [severe] earthquakes in various places" [Matthew 24:7], "distress of nations, the sea and the waves roaring"—tsunamis, hurricanes—Luke 21:25, but this is good news if you have put your trust in the Lord Jesus Christ, for "when these things begin to happen, lift up your heads [and rejoice] because your redemption draws near" [Luke 21:28].
