    We are in the process of purchasing 5 db gain external antenna to improve reception on our GSM/GPRS motorola modems. We use them for data transfer and data reception country wide.

    Does anyone know the central frequency used in Ireland. We know it in the 900 to 950 mhz band. Our antenna provider ( Procom ) need to know the central frequency so as to cut antenna to best gain.

    Have tried O2 and Vodafone tech support but no sucess:confused:

    Sounds like he wants to tune the antenna to a specific service provider frequencies on the TX side.

    Below are the RX / TX bands I am aware of, but I don't know what the service provider allocations are within these.

    The service providers should know but you would have to contact the "radio planners" for specific information, the general technical area is too broad for this specific query.

    My supplier says he could solve your problem

    Contact paul Murphy RF Solutions apm@eircom.net
