humax recorder. explanation please

[davyboy 18]

I am connecting this recorder to my new TV.

The manual states:

The cable from the aerial plugs into the Rf in port in the back of the box.

The recorder also supports loop through functionality.

If you would like to receive  a direct signal back into your TV connect an aerial cable to the back of the TV and the other end to the Rf out port at the back of the box.

 

Can someone please explain  what the advantage of this would be if any?

That might just be with Sky boxes.

My Humax box will record 2 things while I watch a 3rd.

Note:

 

Signal strength IS impaired if the Humax box is switched off whilst watching through loop.

I agree, the box works well as a booster. Mine is never fully shut down, just in sleep mode.
