Usually a single LED that flashes with each discharge.
These circuits are generally very efficient, often running on a 9V battery for months because they remain in a low-power "waiting" state until a signal is detected [2, 4]. Practical Limitations shema indikatora grozy
It is critical to note that these devices do not protect against lightning; they only indicate its presence. If used with an outdoor antenna, proper grounding and lightning arrestors are mandatory to prevent the device itself from becoming a fire hazard. Verdict Usually a single LED that flashes with each discharge
The effectiveness depends heavily on the antenna length. A longer wire increases range but also increases the likelihood of picking up industrial noise [3]. Indication Method: shema indikatora grozy
