How to PreTune a Ham Radio Antenna

Hi I'm N7QJM, Kurt for Expert Village. We're continuing our session on finalizing the actual operational aspects of the antenna. So we're going to actually tune to the frequencies of the particular band we can operate in as a general class licensee. And we will tune the antenna to make sure that we can have optimum performance going out into the atmosphere so that we can get contacts on our ham rig. So stay with us. Now we're going to tune to this lower frequency here which is listed right here on the twenty meter band for the general class license. And we will see now if we can actually operate on this. What we need again to do is go back into this tuning mode, which is the CWM is for tuning this particular rig. Now I don't know if you can see this very well, but what I'm going to do now is tune off of the antenna tuner and we're going to see if we get good reflection going out. Now this crossing section is know as the standing wave ratio and that's what you want to see when you tune the antenna. You notice that this frequency, in the twenty meter band is tune very very well. One thing you want to do is make sure half way into the band as far as I can operate, and you always want to listen first to see if there is anybody there. Now we'll switch it back and we'll check this up here again on the tuner. Okay, the wave ration is looking even better than it was before so we're in good shape there. Let's tune it to the top end of the band, and we'll go from there. Now we're at the top end of the band, 350 on the twenty meter band, and we'll try it one more time. We'll flick it over here and now we'll watch up here on that meter and we're ready to test it, let's see it looks. We're pretty good, but the standing wave ratio has gone a little higher. So you want to listen first and then you also want to make sure that you're tuned. We are now ready to run Q-sos or we'll send that out into actual broadcasting our station. Next time Expert Village, this is N7QJM 73's.
