Im using a RUT240 for a remote camera location. The mobile signal and internet speeds seem to vary greatly, from usable images to the connection dropping out all together. Signal strength varies between -50 and -70 db. As antenna I use a Cell 6138 4G/5G antenna. It has two cables marked H and V, supposedly for horizontal and vertical polarization. How does the RUT240 use its antenna connections? Does the software switch over from MAIN to AUX when the signal drops below a certain level, or are they used simultaneously? Can this be the problem why my connection seems to be very erratic, with very good performance on some occassions and hardly any connection the next moment?
