I just installed this on Saturday, and it pulls in the local NBC affiliate much better than the Clear Stream C4 that it replaced. Unfortunately I lost PBS, which broadcasts in the VHF range in my area...probably because of the angle where their broadcasting antenna is located. But I'm more concerned about watching SNF without massive breakups and freezes, so I'll just watch PBS on the web as needed.
Assembly took about 20 minutes, but mainly because I wanted to get it right. Others should be able to get it assembled in 10 minutes.
Note: You will receive an email receipt for your payment, and then you will not hear from them again. If you ping them asking for a tracking number, they will not reply. But it arrived for me after 8 days.
