Long time, mostly lurking member with few posts and I have a peculiar problem. For some time I've been looking to replace a 20 year old, well weathered ChannelMaster antenna. I found good deal on the Clearstream 2 antenna at Costco. I did a bit of research and thought it would work for our situation. It has a 50+ range and we are located about 35+ miles from where all broadcast towers are located. Naturally, after purchasing it, I find out that three of the major TV stations in our area are still broadcasting in the VHF range (according to Antennaweb.org), which the Clearstream won't pick up. These stations are 8, 10 and 12. More about them later in the post. I debated about whether or not to try out the Clearstream or just return it. I decided to try it out. I left up the old antenna in case the Clearstream didn't work out, and rigged up a temporary pole to mount the Clearstream to. The Clearstream is about three feet higher than the old antenna. I switched the cable from the old antenna to the Clearstream. Inside, I checked out reception on a Toshiba in a bedroom, a Samsung in the living room, and an ElGato EyeTV unit on a Mac mini attached to the Samsung. Surprise, every station continued to come in and, according to my wife, some looked better than before. For about 30 minutes. Then the Samsung and the EyeTV unit stopped receiving two of the three VHF stations… but not the same two. I rescanned channels on all three devices. The Samsung picks up channel 10, but not 8 or 12. The EyeTV picks up channel 12, but not 8 or 10. ??? Meanwhile, the Toshiba continues to receive all channels. More ??? I fond all this odd because the antenna cable goes to a digital signal splitter in the attic where a separate cable (of the same make and length) goes to each device. Any ideas on what's going on and/or suggestions to fix? Or should I just say forget it, and return the Clearstream and buy a new ChannelMaster? Many thanks.
