When you have a weak signal reception, please refer to Improve Weak Signal and adjust the direction of the flat sides on the default Omni antenna to get a little better signal reception.
If the signal is very poor, please consider upgrading the 4G mobile antenna with a higher-gain antenna. The directional LPDA antenna and MIMO panel antenna can point towards the cell tower and receive stronger 4G signals.

A 30-feet LAN cable is included in the package. You can use a max 320-feet LAN cable between the PoE adapter and outdoor router.
If require a longer distance and reduce the signal attenuation, you can use the PoE extender to get an extra 320-feet distance.
