Working Principle

The V640-HAM11-ETN is an active antenna, meaning it amplifies the signal it receives before sending it to the receiver. Unlike a passive antenna, it does not rely on reflectors or directors to enhance reception. Instead, the antenna uses an amplifier, which increases the signal before it is received by the receiver.

The amplifier is powered by a 9V battery. The battery powers a transistor, which converts the low-level signal picked up by the antenna into a higher level signal. This amplified signal is then sent to the receiver, where it is decoded and understood.

The V640-HAM11-ETN active antenna is a reliable and easy-to-install way to boost signal reception and optimize signal usage in a variety of applications. It is an invaluable tool for any operator, whether they are an amateur, professional, or military.
