Sébastien Lorquet squalyl at gmail.comA N connector is designed for 1KW power and is half an inch in diameter :) ... It seems difficult to find the exact type of this connector even if it's present on a high number of phones. It may be a MC-Card, Hirose MS-147 is also probable: http://szwholesale.com/ebay/2/Antenna/3G-combination/antenna_connector-1.jpg You might find a short pigtail that converts this connector to SMA, then a more classical SMA-anything , maybe SMA-N or SMA-BNC followed by BNC-N.
