Kindle 3G antenna hack

kindite · 03-25-2011, 09:10 PM

For fringe coverage situations, has anyone looked at doing a Kindle 3g external antenna hack? This is a screen shot from ZDnet's Kindle 3 teardown

The Anydata quad-band 3G radio uses a "hirose, u.fl-r-smt, 50ohm" SMT connector, which seems quite standard, according to AnyData's specsheet.

Any number of stock quad-band hi-gain antennas should probably work with this, I would assume.

coupled with something like this 8-inch U.fl to N-Male 8 Inch Cable for 6 bucks: http://www.wlanparts.com/product/CA1...nch-Cable.html

I don't think you'll get any better coverage with an external antenna.

Hmm, this is the kind of hack that Kindle are bound to notice. I doubt even the most hardcore software hackers will want to do this.

Not sure how they would be able to. The radio and software isn't altered in any way - just the piece of metal that's between it and the cell tower. Also, the only hardware change-up would be disconnecting one cord and (with a small hole on the back of the Kindle, void warranty of course) connecting another one. Nothing in the SIM card is touched.

that's definitely true in the city or other dense area. My thought was something like a really high-gain antenna in a very rural area. Something like this 10dBi quad-band patch antenna:
