Routerboard hardware interference with Midband 2-way radios

We have just had to replace a routerboard, that was generating quite a bit of interference to a Midband transmiter mounted on the same mast.

This wasnt interference caused by the radios on the routerboard, but the actuall routerboard.

Its now fixed, but I am concerned about other sites I share with 2-Way radio operators.

We solved the problem, by building the Routerboard into a shielded Aluminium box, before mounting onto the Antenna Mast.
