Chapter 2: System hardware 91
The locally sourced steel lightning rod needs to be minimum 4 feet long, maximum 5/8 inches thick and
secured with two separate hose clamps and should be at least 0.5m higher than the top of the omni, with 3
feet (1m) over the top as a maximum. Either type of lightning rod can be used, the single blunt tip version
or having a dissipator on top (the dissipator concept has many smaller rods clustered together so they
have many weak streamers instead of one large streamer which would attract a lighting hit better). Below
is a recommended example from the LBA Group, 5 feet long, 5/8” O.D model DAT-160SS.
It is mandatory to have the mast grounded, if this is not possible a 6 -8 AWG Cu ground wire needs to
attach to the lightning rod base and run down to the ground (PE) bonding point.
