4 Stars good & functional, but insufficient assembly instruction
My location is in Salem, Oregon, with most TV stations being 45 miles away in the Portland area. [...] recommends a “multi-directional”, so I bought this DB4 from Amazon. It came pre-assembled, and is functional from start on the roof, picking up 2.1, 6.1, 6.2, 8.1, 8.2, 10.1 through 10.4, 12.1, 24.1 through 21.5, 32.1, and 49.1, showing a signal strength of around 70% on my digital converter box. But it can pick signals only one direction (3 degrees apart), and it cannot pick up 22.1 though 22.4 (same direction and distance). Amazon is kind enough to let me return it, and even pays for the return shipping.
I then bought a directional antenna of the same range, Philips Sdv7400K Outdoor Antenna, also from Amazon (but sold by another vendor). This Philips antenna requires assembly and very careful study of their manual and diagram, but once it is up on roof, it picks up 22.1 though 22.4, as well as all others that DB4 is able to cover, with about the same signal strength. So, I am giving DB4 four stars because it is not really multi-directional as it claims. Cost-wise, DB4 is about [...] more than Philips Sdv7400K, but is a lot easier to set up. However, it does not include a full set of mount kit as Philips Sdv7400K does. Besides, if you want to return Philips Sdv7400K, you will have to pay for shipping and a 15% restocking fee.
So, it is safer and easier to just buy whatever Amazon carries themselves, like this DB4.
