Product description The RF-AB Radio Frequency Switch from Contemporary Research is a self-terminating remote controllable RF (Radio Frequency) A/B switch. When used with the CR 232-ATSC+ HDTV tuner (not included), this unit will automatically switch between air and cable RF feeds. The included 3.5mm cable connects this switch to the A/C jack on the back of the tuner. It correctly handles RF signals by terminating the RF feed when it is switched off. In addition, the switch will default to the cable input when there is no DC power. - Compatibility
- Connects to 232-ATSC+ HDTV tuner for integrated cable/air channel tuning
- Switches two RF feeds to one output
- Terminates RF inputs when switched off
- 2.5 GHz bandwidth allows use for air, cable, and satellite RF
