Does it matter which way a MagLoop directionally faces?

The Alpha MagLoop antenna has an approximate 8-degree directional null, which tapers then increases in signal strength as you turn the antenna through that null. In practice, you will notice a weaker signal as you get to the center of that 8-degree null. Once you get to the center of the 8-degree null you will notice the signal is about 5dB to 7dB less than off the edges of the loop. As you turn 4-degrees in either direction out of the 8-degree null, signals begin to get progressively stronger.

The impact of surrounding objects

Surrounding objects can also cause a different result, which is dependent entirely upon how the environment is affecting signal pattern of the antenna.
