Space combining can be an effective technique for selectively adding channels and/or increasing power on a specific point-to-point path. The technique was adopted to feed one of several AML receive sites with a different channel line-up than the others.
The additional channels required at the site were fed to a separate broadband transmitter and connected to a separate antenna which illuminates the particular receive site. The channels are received in their respective frequencies by the standard AML broadband receiver, combining in space with the channels already being sent to this and all the other AML sites.
Cable AML’s model ITX-100 power-doubling transmitter was used for this application due to the high power required and the built-in redundancy of this type of transmitter.
