VA20B

The ELAN VA20B is a bi-directional RF amplifier designed for use in distributed CATV systems - Bi-directional: It can amplify signals in both directions – the forward path and the return path.
Return Path: It has a return path frequency range of 5-40 MHz.
Gain: It provides a 20 dB gain.
Ideal for Distributed CATV Systems: Its characteristics make it well-suited for use in systems where the cable signal is distributed to multiple locations.
In essence, the VA20B helps boost the signal in a cable distribution network, particularly for the return path which is crucial for interactive services like internet and telephony over cable
