Coaxial Connectors (RF) - Adapters

19K119-K11L5 application field and working principle

A 19K119-K11L5 adapter is a coaxial connector used for connecting two different coaxial cables. This type of coaxial connector is suited for low-voltage signals, and is widely used in radio frequency (RF) applications. It is most commonly used for connecting ham radio antennas and other wireless communications devices.

The 19K119-K11L5 adapter uses a threaded sleeve-lock assembly to ensure a secure connection between the two coaxial cables. This type of adapter allows for a quick connection while maintaining a consistent electronic performance for both devices. The threads are designed for standard ¼” size cables and the sleeves provide a secure attachment for a reliable connection. The design of the adapter also makes it easy to install, which reduces the amount of time needed to complete the task.

The 19K119-K11L5 adapter is designed for low-voltage applications, such as Ham Radio antennas or other wireless communications devices. It has a power rating of up to 250 watts and an insertion loss of less than 1.5 dB at 100 MHz. It is also designed for 50Ω impedance. This ensures that the connection is both reliable and compliant with standard frequencies.

The 19K119-K11L5 adapter is also resistant to corrosion and oxidation, making it suitable for outdoor use. It features a dielectric material that provides a stable environment for the electrical connection, and a nickel-plated brass body that resists rust and corrosion. The connector also features a foil shield that protects against interference from environmental factors.

The 19K119-K11L5 adapter is an ideal solution for wireless communications applications. It is easy to install and provides a reliable and secure connection between two coaxial cables. The adapter is resistant to corrosion and oxidation, making it suitable for outdoor use in harsh environments. It also has a power rating of up to 250 watts and an insertion loss of less than 1.5 dB at 100 MHz. for 50Ω impedance.
