The amplifier works great. My cellphone is a Nokia 3589i with Sprint. Because the coupling device is not so good and this model does not have an external antenna connection, I was requiring the amplifier. I have a PCS panel on the roof and a long cable down to the office. Now with the amplifier I have signal inside the house. Thanks,

I did a test drive today with the 5300. I drove from my house onto farm hill to 280N to San Francisco and was on a conf call for about 35min. I was not dropped once during that time period.

We have installed the boosters in our police squad cars attached to Sierra Aircard 555 modems and have had a very significant increase in signal strength in all areas of our city. We are using the modems for data traffic.

Good news! We tried it (CM2000) over the weekend and it came in very clear.... We're very thrilled to be able to communicate in this remote area. Many thanks!
