Freeview signal strength.... nightmare...<br><br>Basically you do what works!<br><br>1) Signal boosters are also signal degraders I'm afraid, they amplify the noise as well as the signal and then add some noise of their own.
<br> I'd try to get rid of them. Freeview doesn't necessarily need strong signals but it does want clean signals.<br>2) A dedicated aerial for freeview helps. Nice new clean connections, satellite grade cable etc etc.
<br>3) Sometimes (esp. with signal boosters) the signal can be TOO strong, in this case you need an attenuator.<br>4) An professional aerial installer can work wonders...<br>5) Generally for analogue TV the signals are constrained to a paricular BAND of UHF
frequencies.g. A B etc. <br> Freeview signals for that area are usually<br> a) At a minimum in a different band.<br> b) In lots of bands.<br> Aerials come specified for particular bands A,B or Multiband (I think this is band X it's been a while).
<br> In short the aerial on your roof maybe fine for you analogue band but rubbish for your freeview channels.<br> So find out which UHF channels your analogue and freeview MUXes are broadcast on and get an appropriate aerial. AND
<br> nice high grade cable and connectors...<br> Did I say a professional aerial installer can work wonders? They have fancy meters to check signal strength at the various frequencies,<br> in different positions on your roof etc etc. It's pretty much a one off payment...

<br>channels, but maybe I need more now that I have the 2 Nova-T cards. I<br>occasionally can't get any signal and have to plug the portable TV into<br>the aerial to tweak the signal strength adjuster on the second booster
