This is extremely frustrating. I installed the exact same devices just as you have in the photo and I get NOTHING. Not a bit of change, no more stations. In the photo, is your VHF antenna pointing at the station off to the left or off to the right? I took a compass into my attic in order to point the antenna in the proper direction assuming the front of the antenna is the left side of yours above. When that did nothing I spun it around in the opposite direction. Also, the other signal combining device has a UHF on and off switch which I’ve tried in both positions to no avail.
