Signal booster for Voda 3G/HSDPA?

Hi all

We use Vodacom for data access at the farm. There is literally no coverage by the other players (CellC, MTN).

I need a budget signal booster so that I don't constantly get signal loss.

Are any of the following units appropriate?

I have an external pole with a VHF omni aerial on it already for the farm radio, so I have a mount point close to the office.
