I hooked up the preamp on Saturday. I could pull the 42's easily (no issues) from the same tower as the 3's but I'm thinking WHSV is having some issues. I see some comments on their facebook about people losing signal. I'm not sure what their issue is but the reception has been more stable since I added the preamp. Their signaling looks to be an ongoing issue even years ago from what I've read so hopefully the preamp will and has solved the problem.
