In most radio transmitting or receiving installations there will be four different types of ground systems to consider and implement:
• Grounding for lightning protection
• Grounding for power distribution safety
• Grounding all station equipment together
• Grounding for maximum antenna efficiency
The first three are absolutely necessary; the fourth may be important, depending on the type(s) of antenna(s) in use.
NOTE The single most important message to take away from this chapter is this: A good lightning ground is not necessarily a good radio ground, and neither of them provides a safe power distribution or equipment ground in and of itself. In short, for a proper communications installation, ...
