Please suggest a good quality 4x1 diseqc switch

[Feku]

Hi Friends

I have one Solid 4x1 diseqc switch which is not working properly for me. Means my receiver sends proper diseqc commands but the switch does not switch the LNB.

Can anyone suggest me a good quality 4x1 diseqc switch for me to replace the above one?
My receiver to switch length is approx: 40 feet

Thank you
