Now that I have an antenna tuner that can handle it, I'm thinking about giving a random wire a try.
At this point I'm looking to run it from the tuner, out the garage wall, up to the roof line, around to the back peak, there I'll support the lower end from a PVC pipe insulator and shoot for the highest point in the tree I can get a line over.
Now, as I understand it, I attach the running wire to the one post on the tuner, the thing I'm not sure of is the ground. Do I just use the grounding for the antenna tuner. I have the tuner connected to the central grounding system along with all my other equipment, with a solid copper wire running out to a grounding rod at the front of the garage. This will put the point of ground at the opposite end of where the random wire will run.
Will I need to add another grounding run around to the area where the antenna will be, add ground radials, or will the central ground I already have do the trick.....?
I read an article by a guy named Jack (VE5EE or something close to that) and he claims in order to make a random wire that will load up for every band, you don't want it's total length to be a 1/4 or 1/2 wave length, or any multiple of a 1/4 or 1/2 wave length to any frequency you want to use it on. He goes on to list a table of lengths not to use, and some suggestions on good wire lengths to use. This has something to do with impedance matching at those chosen frequencies......
Anybody have any thoughts on this....???
