dc blocker location in amplified antenna setup

[bignaz]

i am connecting a amplified antenna to a hopper. i am getting conflicking info online on dc blocker locations.
what location would the dc blocker go if i am using a OTA dish adaptor, antenna amplifier and dc blocker.
some info i've seen says after right antenna and some say between ota and hopper. i i would think it would be between amplifier and OTA dish adaptor.
can someone shed some light on this. thank you for any help you can provide.
