Detroit Packing Co. High Gain 28dB Magnetic External GPS Antenna Cable - 7.5m (25ft) Straight SMB Female Connector - Compatible with Verizon Samsung 3G Network Extender Review

Works well for amplifying the satellite signal on my AT&T Micro-Cell. I highly recommend this to boost the satellite signal for any compatible device.

I bought one of these antennas for a Ford Sync 3 conversion but had a navigation error during startup so I bought a second one (just thought the one I got was was something – something broken) and it does the same thing. I bought a third one off eBay (instead of the L connector) and it works great. If you're doing a 3-sync conversion, I wouldn't do it

Instead of replacing a broken Audi Sharkfin GPS antenna (dealer wanted $800) I just unplugged the stock antenna on the back of the radio. I then hooked up the spare GPS antenna to the back of the radio and found a suitable location for the receiver above the glove box and just below the dash. Worked perfectly. Hard to beat for the price. A $10 solution that works just as well as an $800 dealer solution!

This antenna worked when it was first connected but stopped working after that. I'm sure some people are luckier than me. They accepted my return. The magnet was very strong and worked well. Also, the cable was VERY long. So if you plan on installing it near the connector I needed (Ford SYNC 3 main unit) the folded extra cable might actually take up too much space all well placed. I then ordered one from uxcell, the cable of which is shorter and looks better with a fabric tape. It still works.
