Lightning surge protection for 3G/4G/5G Radio Cellular Masts

Paul R

 I need advice please  on the appropriate area of BS 7671 / IEC specifications which outline measures Cellular Radio Antennas ., especially for temporary Base sites placed to provide additional coverage (as in stadiums, concerts, county fares etc.

    Do you actually mean the antennas, or the power supply to the base station electronics. 

    BS7671 does not have a lot to say about the former, and as far as  the latter is concerned may be TT or TNC, and then as far as the mains supplies are concerned it is SPDs and filters.  

    How is the back-haul link being provided ?

    The antennas, lightning,  and the earthing system will need to be considered as one, depending on the location it may well be the largest lightning conductor for quite an area unless you try and design it so something else is instead.

    Mike.
