If you have interest in the information supplied by me,you can make a advance contact with skycore.sogou.com !

Hi liutengji,

Thank you for your reply, i need the antenna to be small in dimension (around 10 cm*10 cm*10 cm), and the gain aroud 5 to 10 dB, and this antenna will be used in new project related to GSM networks. but the important specification i need for this antenna : dual band(850\1900), dual polarized, directional, small dimension.
If you have a product like these requirements please send it to me.

Best Regards,
