[TowerTalk] Lightnig Arrestors at tower base or house entrance?

[Bill MacLane]

The commercial stations where I have worked have the towers protected at each tower to the ground system. The transmitters are also grounded to the ground system.  Surge protectors are on the power at the service entrance, grounded at the service entrance and bonded to the ground system to meet requirements of the NEC.  A,M. towers are protected with arc gaps and un-tuned F.M. are directly grounded with ground straps to the ground system

At my QTH I do the same.  I also have surge protectors throughout the house on electronics items.  These are not the cheap chineese kind, but good ones that have more than an MOV or capacitor in them.  Most are active line conditioners/surge protectors.

Remember surge protectors are just that. Protection against line surges.  There are also line sags that can damage equipment. Lightning protection is to prevent or reduce damage caused by lightining.

I plan on having the coax shied grounded at the top of the tower, bottom of the tower and at the house entrance.  But where is the best place to put lightning arrestors?  The run from the tower to the house will be about 30 ft. and will be buried.  

Thanks,
