shampoo

Can anyone tell me what adapters its compatible with ? i noticed in some of the threads the Alfa AWUS036NHA is, i'm curious about the AWUS036NH too has anyone had any experience with this adapter ? I want to use one of these is possible as a repeater linked to pineapple. I have tried the Alfa R36, but the throughput trade off is stupidly low, it takes a 15MB per sec signal and turns it into a 2MB per sec, a bit of a let down. Any help or advice would be appreciated....TIA
