| 1291244 | 2012-07-28 03:18:00 | howdy, I'm trying to hook up a UHF aerial and am only getting 4 channels showing as available, and all of those are unwatchable as it is. I've made sure the aerial is orientated correctly, both pointing at source of transmission & aerial is orientated like an arrow pointing away from source when viewed in plan (top down view). Is there anything else I can try before I call in the experts to fix it? Anything obvious to try? Reason this is urgent is I only have a few hours of sunlight left before I must put back the old analog VHF aerial. Thanks |

| 1291245 | 2012-07-28 04:17:00 | Have you tried turning the aerial 90 degrees (so it looks like this from the side (<-x-x-x ..........transmitter) instead of the top (horizontal instead of vertical orientation))? Where are you?, a location may help. These guys may be helpful www.nzdtv.com |

| 1291246 | 2012-07-28 04:25:00 | yup, tried that. When it was looking like this in elevation <-X-X-X we received zero channels, then when it was rotated to look the same BUT in plan, we received 4 channels (well, it said we did however they are so distorted it might as well be static....) |

| 1291247 | 2012-07-28 04:41:00 | Are you talking digital or analogue signal reception (Freeview versus old system (no settop box/decoder involved)), if analogue you will need VHF aerial connected/mixed as well to receive all channels. As well as that, analogue transmissions will cease this year or next (depending where you are), so if you are still using analogue, you'll need to update soonish (poss a good idea to get a professional aerial/system installer to advise/help you). |

| 1291248 | 2012-07-28 05:19:00 | Tivo unit is the tuner, it didn't' give me a digital or analog choice, I think its because tivo is digital only? Aerial does have a splitter, didn't think it would make that much of a difference. Also tried rotating in multiple directions, and double checked none of the outer strands or foil were touching centre prong. I'm done - time to call in the professionals! Thanks anyway everyone, really appreciate your help! |

Thanks anyway everyone, really appreciate your help! Did you check the "district average" i.e. take a look to see where all the other aerials in your street were aimed? From that you can tell whether your antenna orientation and polarisation are correct. However, the most likely problem is that you are trying to feed the TIVO output into a TV channel that is not yet tuned to the TIVO output, instead of using a TIVO AV output to feed an AV input on your TV. If so, then once you changed the antenna connection your normal reception went down the dunny. I don't know anything about TIVO units but all my decoders have an AV output and the TV just acts an a dumb monitor. Took me ages to convince the family to use the old remote solely to switch on the TV, then to control everything else with the digital tuner remote. Cheers Billy 8-{) |

| 1291250 | 2012-07-28 06:18:00 | Thanks Billy, But I directed it the same was as several neighbours and still no dice! Yes, the Tivo is doing all the tuning and the TV is just a monitor - even then the tivo only picked up 4 channels (even tho they were all unwatchable, strange thing was the signal strength indicated was about 70-75%?) At least I gave it a good shot, don't mind paying a pro now. Thanks everyone |

| 1291251 | 2012-07-28 07:02:00 | The end with the shortest rods should be towards the transmittion source. If yo do not have a free view decoder you will only see a couple of uhf analog channels. Also you need a better coaxial cable then for tv1/3 unless you are in a good signal area. i.e. can see the transmission tower. the antenna elements should also be horizontal. If they look like a wide "H" then they should be so that the H is onits side. piva howdy, I'm trying to hook up a UHF aerial and am only getting 4 channels showing as available, and all of those are unwatchable as it is.

| 1291252 | 2012-07-31 01:48:00 | OK, now we are getting somewhere! 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!) I plan on buying the cable myself, (testing the aerial on the ground to make sure the aerial works first), install a new UHF capable splitter & try to get this going myself (worse comes to worse and I have to call in a pro to fix it all: at least I tried and have the gear to keep the costs down). So I have a few questions before I start: 1/ Is there any reason to use a horizontal splitter over a vertical splitter apart, apart from the orientation of the cable outlets for mounting? (basically how do I know which one I need: horizontal or vertical?) 2/ How important is using a weatherproof cover for the splitter, if I intend to mount it under the house (protected from rain etc). 3/ I'm looking at getting quad shield cable, how much of an improvement is that over duel shield? Is it *really* going to be that noticeable? 4/ Can the UHF & VHF aerials be mounted on the same mast OK without interfering with each other? Was thinking may as well enjoy both (able to record more channels at once) until analog is cut off anyway. 5/ I've seen splitter refered to as 'power pass all ports' what does that mean exactly? thanks |
