Greetings,
I would like to assemble a HD PVR possibly using this card with my computer. I just purchased a LG plasma HD TV it has a it's own HD tuner plus NTSC tuner which I want to use to capture OTA signals. I have heard this ATI card is having it's problems. Has anyone have personal experience with it and is a software problem? I heard of the Fusion HDTV 5 Gold is a good tuner, but I can't locate one hear in Ontario. I would also like to purchase a UHF outdoor antenna (CHANNEL MASTER OR OTHER MANUFACTURES) anyone know where I can get one in Toronto or Mississauga? I'm trying to avoided the costs associated of having to pay the monthly bill for the HD signal to the cable company. Any help or recommendations would be appreciated. Thanks! Newbi Wishing you all HAPPY NEW YEAR! J Poy |

It depends on the distance between the antenna and your receiver. Reception is all about signal to noise ratio. If the preamp is noisier than the front end in your receiver (likely) then your reception will suffer. |

I want one that functions. I don't know what dollar store crap you have been looking at. |

Whether that will be rendered immaterial by overload is a very different matter .... receivers are usually better than preamps in that area. Doug McDonald |

No expierence with any HDTV product but I do use an ATI-TVwonder card, works great, installation was straight forward and performance has been "As Advertised" It currently records a show for a friend, I deliver on a different HD product (Hard Drive) every couple of weeks. Hauppauge also makes a good card from what I'm told (Win-tv) Do not know if they make an HDTV product... Their new line should come with some very familure feeling software in it's box. Now: The antenna... Channel Master is a very good antenna company. You should find a dealer listed in your local phone directory, That is about all I can say.. You can do the net search but I'd find a local dealer, I'd also go to multiple dealers. I used their best antenna atop a 100' tower at my parents house, Which according to the Television coverage maps should NOT have been able to watch anything but snow (And this time of year we could see all the snow we wanted and then some without the need for a tv We often watched shows broadcast from over 100 miles away (over 140KM)and got good reception as well. Of course... Took two of us to erect the tower and put the antenna up there, The system used a head end amplifier, coax feed and a distributation system so we could watch at a number of different places in the house,,, very professional instalation... I should know.. I did it. -- John in Detroit E-Dress is smoked, try: w a 8 y x m at a r r l dot n e t |

Actually,,, With Channel Master's top end antennas that is not, entierly , true. You see, the top end antennas have a compartment at the head (antenna) end, this compartment contains either the proper matching balun (300 or 75 ohm) or a pre-ampolifier (and CM's pre-amps are very good, at least in my expierence, which I'll admit is some decades old) So, if you are willing to climb up the tower (I was, even if I do suffer from acrophobia, let me tell you, 100 feet up, even with a safety belt, was not exactly fun) to pop in the head end unit, you can put the antenna up, make sure you put a junction or other device where you are going to put the power adapter (In my case in the basement), next to the power mains) you can always after-instalation climb up and make the change. now... Where I'm at now (Detroit) I'm only a few miles from most of the major television transmitters... If I put a pre-amp in I have to be very careful to avoid front end overload (That is, I can use one, but only if there is a distrubution block downstream, at least a 4-way splitter or don't use a pre-amp) Thus, I have 2 antennas on this house, both split two ways -- John in Detroit E-Dress is smoked, try: w a 8 y x m at a r r l dot n e t |

PARTICULARLY in the digital realm as ghost signals, reflections, etc. are not a problem as they are in analog reception. |

A digital signal that is too strong can be just as problematic as a signal that is not strong enough. If the signal is too weak a pre-amp can help, but remember that the pre-amp will amplify any spontaneous noise along with the desired signal. If the signal is too strong an attenuator can help but remember that the attenuator will weaken the desired signal along with the ever-present noise. The goal is to have a signal that is strong enough to provide the desired signal to the antenna input but not so strong as to overload it. When I first installed an 802.11g wireless connection on my computer, I spent the first few days cursing it and throwing objects at my computer. It had intermittent lockups and crashes requiring many "power off/reboots", I re-read the instructions many times over to no avail. I began to think that I had gotten a defective part .... either the wireless router itself or the USB wireless device that communicates with it. I tried re-positioning both devices many times. It would work great for a few hours and then it would lock up. I finally came to the conclusion that my signal might be too strong. When I installed the wireless router, I had shortened the coaxial cable by about 75 feet and moved my cable modem back to the corner of the house nearest the point where the cable service entered. Just to check out my theory, I coupled in about 75 feet of extra coax between the cable service entry point and the cable modem to serve as an attenuator. I rolled the excess cable into a neat roll. An tiny attenuator would have probably worked as well but I did not have one handy. I have not had a single problem since. It has worked to absolute perfection. To summarize: I have been a liscensed Ham Radio Operator since 1958 and I had a 37 year career as a computer engineer with IBM Corp. I say that sometimes a preamp will help but there are times when a preamp will make matters worse. PON |
