I just passed both my Technician and General Class license this past weekend, and am now contemplating my first station. To get my feet wet I'm planning on getting a Yaesu FT-7900R Dual band Radio with a yet to be named power supply (probably a Samlex SEC 1223). I plan on installing a DBJ-1 from Ed Fong. He has stated to me:
The antenna is DC grounded so no lighting arrestor is needed. All you need to do is to make sure the shield is grounded (which I assume it is from the power supply). Nothing will protector your antenna from a lightning strike. So yes, if you see a storm coming it would be advised that you disconnect the antenna from you radio. All a lightning arrestor does is to DC ground the antenna which protects your radio with high voltage spikes induced by the lighting. Our antenna is a DC ground antenna so it already does that.
I plan to operate in this manner for about 6 months or so until I can get my first HF rig. I am setting up my "shack" in a bedroom on the west wall of my house where there is a window and an input for my Fios TV cable comes in from the outside there also. I want to make sure that my station is properly grounded for the current configuration but also for my future expansion.
Outside the wall, there's about 8' to the neighbor's wooden fence, and a fairly big tree on the other side. So I won't be able to just go straight up to the roof with my antenna. I live in North Texas, in the Northwest part of Dallas County, so during the April-May time of year we do get our share of severe thunderstorms with lightning and hail, though in 30 years we've never taken a hit around our area.
What would you suggest that I do to begin a good grounding system? I do have a computer that I'll be using, the power supply, the FT-7900R and that's pretty much it. I have a surge protector that's plugged into my home 3-wire socket.
I have SOME room outside, but not all that much but I COULD drive copper rods close to the house if need be. I've ready all about these very elaborate grounding systems, and I'm honestly not sure I have the room for all those things at my house!
