Sanny Telecom's Rubber Duck Antennas are designed to mimic a base-loaded whip antenna, but in a much more compact form. A base-loaded whip antenna is a monopole antenna with a loading coil at the base, which helps to electrically lengthen the antenna. This allows the antenna to be physically shorter, while still maintaining a resonant length for efficient transmission and reception of radio waves. The compact size and portability of the rubber duck antenna make it ideal for use in portable communication devices and wireless networks. It can be easily attached to the device and does not require any additional components or wires. It is also more durable than a full-sized whip antenna, as the protective jacket helps to prevent damage from being dropped or bumped.
