A combination of a 16 channel transceiver stripline array with a close fitting 5 channel receive loop array for non human primates applications is presented. The coils are arranged to allow simultaneous reception with all 21 elements and combine the benefits of close fitting receive only arrays with multi-channel transmit arrays. For a reduction factor of 3 the average g-factor for the combination of 16+5 receiver channels improved to 1.62 compared to 2.66 for the 5 channel coil.
