Sdrplay2: signal dropped by 80 %... what can it be ??

ALA1530 and Sdrplay2, connected to Hiz ?

Hello there,
what's the best way to connect an ALA1530LNP to the sdrplay2 ? The ala1530 has a 50 ohm bnc connector and I assume that, for 0-20 Mhz, I have to connect it only to the Hiz input... Shall I use a 9:1 balun like the Nooelec one ?? ? Thanks a lot ;)
