How do you connect in Saorview and Freeview Terrestrial ariels into one TV?

Goreme

A friend of mine has moved into a house in north Louth. The house has a Saorview and UK (Freeview) ariel on a chimney. She has this TV which the interweb says is Freeview (and presumably Sorview) ready.
How does she connect both ariels up to the telly in order to get both free terrestial regions' TV channels?

The cables from both aerials would usually be combined together using a diplexer which outputs both sets of frequencies on one cable. The diplexer usually is mounted on the pole and resembles a small square box. Has she tried connecting to an aerial wall outlet and doing a channel scan?

No she hasn't tried yet, but I will tell her she should be able to connect both leads into one connector and then have that one connector then single input to the TV.

Are you saying there are two separate cables one coming from each aerial into the home? As I said usually they would have been combined into one downlead when the aerials were installed. If this is not the case perhaps it would be better to obtain the services of a professional installer as if she has no experience it is unlikely she is going to be able to source and fit a diplexer.

I don't know if they are combined into one downlead - she just said there were two ariels on the house. But I'll pass on your comments and maybe she will need to get an installer in to connect it up for her. Thanks Ariyah Shallow Stitch.

Maybe something like this, if she has two cables?

or something similar from these

Note: I have no idea if the frequencies of Saorview and Freeview might clash.

Stop sending the lady haywire with that ebay junk !. In north Louth you will most likely need to have an AMP on your Group A Antenna for freeview Divis - This means there should be two boxes on the antenna pole - an Amp below the large aerial and a diplexer below that to which both antennas are connected - inside the house there should then be a 12V power supply (to send power to the amplifier through the coax) - sometimes Internal distribution amps can have a 12v line feed for the antenna built in. There are many different combinations of this and plenty of antennas in Dundalk for example use the Freeview Lite service from Camlough in group C when Full Freeview is available nearly universally from Divis in group A. Unfortunately there are no longer any competent TV installers left in the area, any that are there want to push their own agenda with Satellite and IP, however, full freeview is possible universally across North Louth with the exception of the south side of the Cooley Peninsula.

Does the house not already use these aerials? Why do you suppose there is a problem?

If the signals are in different groups, you should use a Group combiner rather than a diplexer because this will solve any problems you might encounter with both aerials receiving the same signals.

They usually have DC pass if you need to use an amplifier on the freeview aerial.

You are not going to get Divis on the other end of the band of an un-amped grouped antenna with opposite polarisation. Divis is H and Clermont Carn is V.
The A antenna will pick up Clermont carn (at around -20db), but we are receiving here, so the signals from both antennas will arrive at the TV's at the same time unless some fluke happens with Coax Lengths cause it to arrive 180 degrees out of phase, however even in such a rare scenario the signal from the RTE Antenna will be enough to overcome this.

One word on Diplexers though - they claim to pass channels 21-40 on the Thru leg and 41-59 on the DC Blocked leg - BUT they have a high fall off rate after channel 32 - meaning that the low power MUX's from Divis/Black Mountain on 33, 34 and 39 will most likely have issues.

How do you think what you term a 'group combiner' differs from what has been referred to here as a 'diplexer'?

You are not going to receive the low power MUX in any case, they are as the name suggests low power, from one twentieth to one eighth of the main channels. I wouldn't choose my equipment even trying to receive them. The OP may or may not have problems with some of the half power channels too.

34 should be fine - and if antenna has good front to back ratio 33 will come through too
