Actually, yes, it would still be a random wire. The actual length is what's supposed to be a "secret". I could have a random wire for use on 80 meter CW, in this case, what does the specific frequency have to do with the random length?
I am suspecting he wants to use his random wire on 11 meters. If so, I suppose it's a good start in his learning phase, but not a good choice for 11 meter performance. I suppose I should have asked "what band".
I've used random wires in the past, but only had decent results when I used a remote tuner. I wouldn't mess with another one unless I had another remote tuner, which I'm currently in the market for anyways.
