Are you talking about the OmniX scanner antenna or the Miltenna Omni? There was a topic here a while ago that had alot of opinions on the OmniX, but it was purged. For the most part, many people commented that the antenna was very well built and had good performance. I can't give any specifics though. I haven't heard of any experiences with the Miltenna Omni. I myself have just purchased the DPD LP antenna and eagerly await it's arrival to see how it compares to the RS 20-176 antenna.
