I don't know your situation, but many folks can get away with using rabbit ears. *It works, or it doesn't. *Barring a serious distance problem, a proper antenna may not be needed. I disagree on the rabbit ears. If you can do an outdoor antenna it's preferable for many reasons like less multipath and stronger signal. If an antenna made exactly for DTV is cheap, then fine. *However, I suspect you may pay extra for an antenna with limited bandwidth over a close out sale on an old fashioned 2 through 82 antenna. If you don't mind the size of the antenna. The Winegard 7694 is only 35" wide vs 110" for the 7082. There is no such ting as an antenna "made exactly for DTV". Antennas cover a range of frequencies thet may include analog or digital TV. Flatness of response and directionality are the important issues and are equally important for analog or digital. G² |

Which will do no good here at all. Post transition our local ABC affiliate is going to VHF channel 5. There is no substitute for the long tried and tested combo vhf/uhf antenna in our area. I see only 1 ABC affiliate going to VHF 5 post-transition and that is WOI-DT ABC 5 in Des Moines moving from UHF 59 to VHF 5. Is that your local ABC affiliate? The FCC database shows WOI-DT with a low STA (Special Temporary Authority) power of 500 Watts on UHF 59 which is a very weak power if correct. The good news to some extent is that WOI-DT was granted their request to run at an increased power of 8.2 kW (up from 3.91 kW) for the post-transition VHF 5 allotment which is a good power level for digital low VHF. In Des Moines, IA, there should be a number of open channels to broadcast on UHF if WIO wanted to. Alan F Yes, that is the station and they have applied for a further increase in power to around 13 kW, but I don't know if it has been granted. So, we do have a low band vhf station that will "appear" in Feb 2009. I am at a total loss to explain why they made this decision...it is likely to reduce their footprint significantly. Channel 8-1 is doing the same thing, moving from RF Ch 31 to RF Ch 8, at the same time. Ch 5 analog has been famous for years here for having a rotten signal. When they went digital to 5-1 on UHF, they skyrocketed and have been solid....now they are going back and probably in the toilet again. Thank God ABC lost Monday Night Football. |

WOI-DT applied for a 11.5 kW ERP on VHF 5 in June, but the FCC has not granted or rejected the application yet. The only real reason I can see for going to low-VHF for where they are is to save money by re-using the VHF 5 antenna & transmitter and for the lower operating costs of low VHF. Their UHF 59 digital signal is out of core, so they have to give that up. If they have interference problems for analog on VHF 5, that won't go away for digital VHF 5. You have 3 stations in Des Moines do a digital flash cut to their upper VHF analog channel. Upper VHF at 174 to 216 MHz (compared to low VHF at 54 to 88 MHz) is considered a good band for digital broadcasting. KCCI-DT CBS 8 will move from 31 to VHF 8 at 23 kW ERP. KDIN-DT PBS 11 will move from UHF 50 to 11 at 19.8 kW, but plans to operate on UHF 50 for a while after the analog shutdown for VHF 11 antenna work (http://fjallfoss.fcc.gov/prod/cdbs/f...bit_id=618292). WHO-DT NBC 13 will move from UHF 19 to VHF 13 at 29 kW ERP. All 3 of them will have respectable power levels for digital upper VHF. I also see that KDMI-DT My Network 56(?) will take over KCCI's RF 31 antenna and transmitter. Good luck with WOI-DT reception after they switch. Alan F |

The "noisy" devices -- motors, CFLs, dimmers, electronic ignition for furnaces -- are the problem for most users. Lightning is a consideration, but not all day and all night, like the appliances. A nice tall tower and a tight coax cable system will help keep out the domestic RFI, but the people who live in town are likely not going to have towers. |
