LTE12 Chateau + iskra p58

Hello how properly connect u mimo iskra 58 antennas? Now i connect existing sma 2x connections in router and set external antenas to BOTH but signal is the same as no antenna connected.

Hi,

Which mobile network are you using, you may need to add additional sma pigtails.

Solved open front panel disconnect stock antenas put existing sma to mimo1 2 and connection on rear panel antennas. Settings external antennas to none but later check another options now speed 81mpbs and 12 mb upload

Glad to hear you have fixed it.
