With a log periodic antenna connected to Tx port (the 850-6500MHz one
from Ettus) everything works fine. With vertical antennas (like VERT900
or VERT2450 from Ettus) the mentioned problem appears.
I suppose that for all antennas that have connection between the active
pin and the ground it might work fine.
