To provide the best performing passive antenna connection, we ran a series of mini-patch antennas through a number of tests and determined the Taoglas Phoenix antenna as the hands-down winner. As with all passive antennas the patch must be aligned with the phones internal antenna which will require trialling a number of different positions. On most handsets we find placing the patch horizontally either up the top or bottom against the back.
Passive patch leads - a word of caution..
By their very nature, passive patch leads can never work as well as a direct connecting patch lead (ie, one that has a metal-on-metal transfer of signal). This type of patch lead simply consists of a coil of wire that acts as a small antenna, as such it's a generic design - the same design used for all phone brands. In comparison a fitted phone cradle has a much larger metal coil that has been specifically designed to match the phones internal antenna, providing far better performance.
We offer this product as a cheaper alternative, but are having mixed results with it's success, so for best results we thoroughly encourage the purchase of a cradle designed specifically for your phone.
What does a passive patch lead do?
Despite not having an external antenna port, this phone may benefit from an external antenna by using a passive patch lead at reduced performance. This type of patch lead has a pad containing a specially designed coil of wire and uses the principle of electromagnetic induction to enable signal to re-radiate from the pad to the phones internal antenna. Typically users experience anywhere from 5-10dB of signal loss depending on the design of the mobile phone, and the placement of the passive pad. To function effectively the pad _must_ be placed directly on top of the phones internal antenna.
An external antenna is used to increase signal strength and quality, which results in faster mobile internet access, increases usable range from a cell tower, improves voice quality and reduces call drop-outs. For more information please see our guide to Passive Connectors.
