(Analyze) Different Antennas, Different Results

We’ve inductively coupled on 33 kHz, a secondary cable (Figure 1). Its origin is the single-phase transformer that you can see in the distance. Now you can see the red paint marks for the secondary service. You can also see red paint marks for the primary cable that is feeding that transformer. These two lines run parallel to one another (Figure 2). 

On the secondary, our peak and null are agreeing. Let’s walk over to the primary. No such luck here (Figure 3). The peak and the null do not agree, and we get seemingly a shallow depth for a primary that could potentially run right underneath that wooden post (Figure 4). That’s not particularly logical.
