This is a discussion on Does anyone know about the new DB8e antenna. within the DTV | HDTV Reception and Antenna Discussion forums, part of the Over-the-Air (Antenna TV) category.
I would like to know how well the DB8e receives high vhf channels.
Eventually I want to mount this antenna on the roof of the house and see how many stations I can receive that I can't receive now (if any). I'd thought about potentially adding another 4228HD, either pointed in the same direction or have one pointed toward Columbus and one pointed toward Montgomery.
The DB8e looks really cool to me, I could point one side toward Montgomery and the other side toward Columbus. But I want those two VHF channels.

I wouldn't expect there to be a major difference in performance between the 4228HD and the DB8e, if that's what you're hoping for. Again, a TVFool report might help us sniff out the other stations in Montgomery and Columbus you mentioned. I doubt swapping in the DB8e is going to give you much joy, unless you weally, weally LOVE the little orange protectors.
Man, those orange protectors are cool! ;-)
As others have said, it's a UHF antenna
But other UHF antennas (CM4228 for example) do a passable job on high VHF
On the DB8 (as opposed to DB8e) the particular PCB balun they used supposedly filtered out VHF while the old CM4228 had a balun that worked fine with VHF
see hdtv primer: DB-8 from AntennasDirect
>> This balun will mostly filter out VHF, so don’t even think of buying this antenna for VHF
Whether that's true for the DB8e, I know not
The DB4e would be a good indicator, since this unit is merely two of them phased together with a reverse splitter.
Note: Those who are using various 2/4/8-bay antennas to receive VHF are only doing so because the VHF station is strong an clean enough for it to be possible, a dedicated VHF antenna will provide better results (and therefore make the VHF stations less likely to be eaten by cable losses, more splits possible, and less likely to need to amplify VHF.)

I live in DVB-T land.
FWIW, there is a tall magnolia tree near the house and I mentioned to my house that I wanted to cut down that tree when I put the antenna on the roof. She vetoed that idea. Maybe I can get away with cutting out the top of the tree.
If a DB8e happens to get VHF, it's by coincidence rather than design. Each of the two halves of the DB8e (a DB4e without the mast clamp, basically) uses the same UHF PCB balun as does the previous generation of their bowtie antennas. The antenna wasn't designed for VHF at all, so don't expect it to do much on those frequencies.
I just got the DB8e up on the roof today. Didn't do much more than that. Both halves are pointed in opposite directions, N & S. It replaced a U75-r that was pointed north and getting the S. towers off the back side. I Lost a few weaker translators to the North, and gained two 1-edge channels from Salt Lake City to the south 73 miles away. These are the ONLY channels I have ever seen from over the mountains.
I'll have more to say about this antenna soon in a blog post / review. (I am still waiting for warm weather. It's cold on the roof.)
I'm sure lots of people are looking forward to it.
I'm likely in the minority, but if I were to ever get a DB8e, I'd be pointing both halves in the same direction and what's of interest to me is how the DB8e compares to the other 8 bays (CM4228, PR8800, DB8)
