| 1291255 | 2012-07-31 02:15:00 | Quad shield is only required if you are going to connect to a cable internet/TV service, for digital satellite or UHF signals dual-shield is fine. Make sure it is Sky approved stuff though. 5. Power pass port means that if you have a satellite set-top-box connected to that port then it can send power to the LNB as the LNB requires power to work and to know which polarity to use (vertical or horizontal) If you want to connect more than one STB then you usually need a splitter that has all ports power pass. Not really an issue for UHF. |

If you have a friendly neighbour with working freeview see if they'll let you take the TiVo over and plug it into their Aerial so you can confirm it's set up correctly. |

| 1291257 | 2012-07-31 11:01:00 | The father in law came round and pointed out the 20+ year old splitter was likely to be the reason I couldn't get UHF reception . (Seems I was so close but yet so far!) 5/ I've seen splitter refered to as 'power pass all ports' what does that mean exactly? thanks None of my splitters are officially "UHF", in fact most date back to pre-UHF days, and nor is my coax anything special . My UHF signal was poor on Prime (maybe because of those splitters) but ok on the rest and Freeview is fine on all channels/TVs, so much so that I've turned the distribution amp down to minimum power . UHF Freeview terrestrial should not be that hard to get, and if your system will supply adequate signals on the UHF analogue channels then it should be well and truly OK . I'd pull the Freeview decoder from the circuit then hook the system back up for Terrestrial TV to see if that is working OK on the UHF channels like Prime . Doesn't matter how many channels you get, just one with average to good picture should be sufficient to clear your signal delivery system . If that works, the problem probably lies in your Freeview decoder or its set-up . 'Power pass all ports' simply means that if you have a back-fed masthead amplifier, the splitter will pass the supply voltage through on any of the output sockets . Cheers Billy 8-{) |

| 1291258 | 2012-07-31 23:28:00 | Don't forget that very soon, or now if you have Freeview, the only aerial needed is a UHF one, so there will be no need for a combiner or anything else. | gneill (5769) | ||
| 1291259 | 2012-08-01 19:38:00 | Saddle clamp type diplexor/vhf/uhf combiners and splitters are the main culprits in many Digital TV reception issues. Ditch the VHF antenna and any splitter or combiner and run 1 new quad core cable from antenna to wall plate or direct to the set. |

| 1291260 | 2012-08-07 01:59:00 | heres an update for those interested: New RG6 cables & power pass splitter arrived last friday, installed all & found still no channels. Determined likely cause was damaged aerial so bought a new aerial to check and BINGO! All channels received and the clarity difference is amazing!! Now have so many hours of TV stored ready to watch, and I'm stoked it all finally works. Thanks to all that offered advice, I really appreciate it - please let me know if I can repay the favour (house plans or renovation advice etc) cheers again guys :) |

Well, that is a pretty rare occurrence, so it was a bit of bad luck for you. It probably wouldn't be the antenna per se, because apart from the driven element (the one with connections) the rest is just a passive collection of metal, but the balun interface to either the driven element or the coax may have been corroded or otherwise munted. Enjoy your new image quality, I know we did when we shifted to Freeview, it was quite a revelation. The only drawback is the slow channel change, you can't surf between channels anything like as fast :D but I guess that is an issue with the decoder acquiring the next channel signal out of the digital gloop. I wonder if Freeview Satellite and Sky have the same delay? Cheers Billy 8-{) |
