    Default Grounding

    I know grounding your equipment is important but does it have any effect on how well your radio performs.
    Thank you.

    Well, if you set aside the safety element, grounding can reduce interference, prevent some types of interference entering the vulnerable parts and can make sure that only antennas are involved in the radiation and the capture of RF. With no grounding, the radio, the wiring, the meters, and even the headphone cable can form part of the antenna. In some cases, the lack of ground also allows RF to be present near the radio that can then leak into other devices. Static build up can also gradually raise the noise level especially at HF but the grounding can also prevent RF burns in some cases, and of course the safety aspect helps to make sure you stay alive.

    yes. Proper grounding improves your operating as well as protects you.
    Understand that there are two types of grounding to think about...standard electrical ground and RF grounding ( I like to refer to the RF grounding as bonding, it seems to help folks understand the difference, especially in mobile installations). Lots of folks run a solid copper wire to a common buss... and that works great for electrical ground, but flat braided wire works better for RF ground. Around your bench do not daisy chain your equipment, run a separate ground line from each piece to your main ground and keep the lines as short as possible.

    Smile Thank you for the information.
