The show I'm on is going to Dubai! We use block 19&21 for cast. Block 25 camera hops and Block 24 for IFB. I have read a lot of people having success with block 21 in Dubai so I'll make that our main block. I would still need six usable freqs from block 19. Is this a bad idea should sub rent another block and pull out my block 19 for this trip.
