I’m putting an OCF dipole, 2 10’steel masts on gables, 1 on a steel mast on a shed 75’. away. It will be coax from the feed point (4:1 current balun), air gap surge coupler before entering house. Coax from there to 1:1 balun near tuner. Everything is grounded to a common earth ground. I’m a newbee, and I’m wondering if and why I have to ground the 10’ steel mast - total height above ground is 26’.

Pls comment

Thanx,

Grounding the mast is a National Electrical Code requirement.

Ground the antenna discharge unit (see Figure 810-7 un810-07 810-20C.cdr), the antenna mast, and antenna discharge unit (ground block) per 810.21
