What are you transmitting to? I've noticed some radios don't seem to pick it up well while others do. Almost as if they're shielded. For example, my Phillips DVD/Tuner system only picks up the signal if I literally hold the CPC (Cellular PC) against the antenna. However my Jeep Wrangler picks up the signal so well I can actually have the CPC sitting in the console between the seats, closed, and it picks up clear as a bell with no interference.
