![]() ![]() Under certain circumstances connecting your equipment to both mains earth and a ground rod could cause issues with RCDs. If you do connect something to it though, MAKE SURE that ground is BONDED to the houses main ground. On todays 12V radios, its really not necessary. In most installations you have a choice between the mains earth or your own separate ground. Back then, A/C plugs were two prong variety, and it was necessary/suggested for safety reason to ground the case. ![]() HOWEVER ! Check your local electrical codes. There should be as many of these radials evenly spaced as practicable and in no event less than 90. This is the method I prefer and I have a 22mm copper pipe running along the rear of the shack table that is grounded to the radiator. b) A ground 'bus' running along the back of your equipment constructed of substantial material, all equipment connects to this including the connection to the ground rod. As for the grounding method there are two schools of thought: a) Separate ground leads all leading to a common point, normally an earth rod. If however you transmit into a balanced load such as a dipole or a beam then the stray RF levels will be lower and you can probably get away with no ground. ![]() If, like me, you are using an end fed wire then there is a possibility of high amounts of RF in the shack so you really need to ground your transceiver and your antenna tuner. The need for a ground depends on your antenna arrangements.
