Ham stick grounding
The first thing to know is that there are three functions served by grounding in ham shacks: 1. Electrical Safety 2. Stray RF Suppression (or simply RF Grounding) 3. Lightning Protection. Each has it's own set of requirements, but not all station setups need every kind of ground. In fact, some setups don't use a … See more After antennas, station grounding is probably the most discussed subject in amateur radio and it is also the one replete with the most misconceptions.

How important is a ground? Most people say that grounding is all- important, but I have had a few people tell me that grounds aren't necessary. See more Grounds fulfill three distinct functions. The best ground for one function isn't necessarily the best for another. The three are: See more WebA trick from the N6BT book is to hook two of the counterpoise wires to an antenna analyzer and trim them like you would a dipole. This lets you dial it to exactly the right frequency given the variability in wire and coupling to nearby things, like the ground. (this is probably overkill for a hamstick).
