Question: It appears that this extender does not connect to the latest model offered by AT&T, Cisco DPH154. Can anyone tell me if This is not correct?
Document: I have both a Verizon and AT&T; extender in the house and for both I had a GPS antenna (the Verizon extender comes with one).The Verizon one picks up the satelites perfectly but this AT&T; antenna didn't work properly (receiving signals on and off) even after I placed the receiver 10 feet from the house facing perfectly clear skies.
I gave it three stars because it is was a good transaction but antenna did not help reception all that much in fact I can not tell that reception is any better at all.Seller did their part though.Thanks
Works great with my Microcell -  Here is a hint, don't tell ATT support you have an extended antenna they freak out. I'm not sure why, they shipped the Microcell with a port on the back for an extended antenna.I just tell them I have a good GPS lock as noted on the indicator lights on the Microcell and move on. I have had zero issues for at least a year.
This antenna is perfect for my AT&T microcell. It does what it's intended to do and the cord was sufficient enough for me to have my microcell located in the center of my house.
It can't boost a signal that it doesn't receive. Still aren't getting a signal from AT&T so not very good phone service in our home.
Long cable included so you can run the antenna to a window. Now my AT&T 3G Microcell works great! Highly recommended.
Connected it to our AT&T microcell and the startup to GPS lock is much faster now, and it doesn't loose GPS and bring the microcell down anymore.
This gadget allowed me to move my AT&T microcell to a much more convenient location and still have the GPS access which is required. A worthwhile investment
Whoever designed the AT&T microcell with an internal GPS antenna should be fired. I had to keep it on a window sill to work. Since buying this add on antenna, it's safely on the shelf and working fine.
I had previously had the MicroCell in the same spot as this antenna, but it didn't work well there, so basically what I am saying is that the antenna works where the MicroCell doesn't. The MicroCell was designed to be used with this antenna, and should never be sold without it (come on AT&T;).
Answer: You are correct... the DPH154 does not have a port available on the rear case surface for the antenna to hook to.  The earlier versions, the DPH151 and DPH153 do have that port available.  Supposedly on the circuit board of the DPH154 there is a port for this, but that is beneath the plastic case, and you cannot open these up without ruining them.  Cisco/ATT has built in security jumpers that fall out and trigger failure codes if the case is tampered with.
