LITEON FlexFi RU configuration

[improperaffo]

Dear all,
We recently acquired some LITEON FlexFi RUs. We followed srsRAN's guide and LITEON's documentation to set up the cells, but we have not been able to obtain good coverage. With the default gain values, the channel is rather poor even at close distance from the RU. We tried playing with some parameters, but we did not have much success.

Does anybody have any good configuration for it? Both in terms of srsRAN configs and LITEON parameter settings.
Any help is highly appreciated.
Thanks
