Is it possible to have 2 TV's with Freeview digiboxes connected to one outside aerial? I imagine the answer has to be "Yes" but "How?" is really my question.
You can also get an aerial booster (or amplifier) that sits up near the aerial (near the chimney for example) and splits the aerial feed into a number of cables.
For example I have an amplifier that sits up near the chimney that splits into 4 cables and sends the signal to four different rooms in the house.
There may be an easier way but I have installed a 'splitter' in the aerial at a convenient spot near one TV and led a length of cable to the other digibox> TV set. There has been no loss of signal strength. I would be surprised if the 'splitter' and extra cable came to more than a fiver.
This comes from a decidely non-technical character so, as I say, there may be other ways.
Have a look on the back of your digibox.You will find that there are two aerial sockets,one in and one out.Just run a lead from the "out" side to the next digibox.[It is called loop-through] At one time I had four boxes running from the same aerial.Give It a try. charleshenry..
