This is what the numb nuts are telling me now! (Nokia).
I tried my mates today and got 1 bar more with both the glass mount and nudge bar mounted 6db than without. That works out about right.
This his how I calculated it (very rough).
We'll go with 2db per bar as described in this post by someone with test equipment.
6db gain from antenna = 3 bars improvment.
Nokia claim RG58 loses 3db per 10ft (about the length of cable on most antennas)
6db - 3db = 3db or a little over 1 bar. (1bar = 2db)
Ergo you should get about 1 bar more with a working coupler and antenna. Which I did using my mates coupler on my handfree kit. With my coupler I LOOSE about 3 bars.
I'm not sure how the coupler works, but I would imagine that GSM and CDMA both require the same impeidance cable meaning (in my lamen understanding) that the coupler should work wheather it be CDMA or GSM...
