The vertical has a 20 db gain over the loop measuring the noise floor. Using the Decca RF pre amp with > the loop gets close to the vertical performance but with the disadvantage of being only bi-directional. Measuring a signal >above the NF indicates the same 20 db gain by the vertical. The band is quiet with no environmental or locally generated >noise problems.The vertical is way ahead of the loop at this QTH. The loop is not worth considering as a TX > antenna given the above results. This recent test confirms previous observations. I see your still having problems with understanding how to connect up to that loop - transformer ratios and all. Don't give up; you'll figure it out one of these days. Bill Ashlock PS: I have to admit my TX loop didn't set the record distance over here this season........... but my 1785 miles came within 35 miles of it ! _____________________________________________________________________ This e-mail has been scanned for viruses by the WorldCom Internet Managed Scanning Service - powered by MessageLabs.
