Can I hold my Yagi antenna to point it in different directions while attempting to tune it to a cell tower?
When you hold or touch a Yagi or any antenna with exposed metal surfaces, your body alters and distorts the signal and changes the antenna’s performance. With a Yagi, Wilson recommends that you temporarily mount the antenna while tuning. It is important that you let go of the antenna when you are taking a signal strength reading or the reading will be inaccurate.
