(Analyze) Receiving Antennas for L/R Guidance: Part 2

The next three receivers that you’ll see will be using this transmitter (Figure 1). It will be transmitting 8 kHz, which is close to the 9.8 kHz that you’ve just seen. This is what we call electronic null, because again, we’re using two horizontally-positioned peak antennas (Figure 2). 

You can see that we get a null. That’s where the line intersects the crosshairs (Figure 3). We get two forms of null here. Watch what happens as we move the receiver to the electronic null reading, We have both a shallower digital depth and a lower milliamp reading (Figure 4). 

So now we proceed to the point where the wire is 10’ deep. The line is in the crosshairs (Figure 5). That’s the null reading. Watch the milliamp reading as we move to the operator’s right (Figures 6-7).
