E.g. the UHF antennas tuned for 14-51, and dual-banders for 7-51. And DTV benefits more from more directional antennas, so even those will end up with sales people labelling them as "DTV". 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. |
