The amplifier I am using is an Astaro HL-105. As everything mentioned on it is in german, I suppose it is a german brand, so I think it would be difficult for you to find one of this type. In order to obtain this amplifier, I simply asked the guys from the cable company and they sold me this one. So maybe someone of your cable company could also recommend or sell you a suitable antenna amplifier.
