We can unequivocally state that the adapter does properly connect to the phone's antenna circuitry. We have tested the adapter extensively with our own Treo 650s and 700s as well as others. We put the phones into field test mode to confirm the improvement in dB signal strength (with external antenna attached.)
To the right you can find an example picture of the results with one of our phones.
Part of the confusion is due to the fact that the signal strength display on the phone, in particular on CDMA models (Verizon Wireless, Sprint, Alltel, etc), is not particularly accurate. Field test mode is a much better method to measure.
