Based on the information provided in your earlier link, it should pick up VHF also. How well? Don't have a clue. I hang our in multiple forums dealing with HD and I have never seen anyone mention this RCA antenna. I use the RS DBT with decent results. It doesn't work well with my NBC so I am upgrading to a massive antenna in the attic. Others I know have great results with this RS antenna.
I'm using the RS Catalog #: 15-1880 as mentioned in the above post. I get great results on the HDTV stations in my area (about 8 miles from the transmitters) but lousy results on SDTV, both VHF and UHF. I'll probably switch to a rooftop antenna combination sometime in the near future since I can't watch ABC MNF on digital (the local ABC affiliate does not have a digital signal here).
