A Simple Topband Upgrade That Made a Big Difference By Bill N6WS So where do I start? The need for a new 160-meter antenna began when I replaced my Cushcraft X-9 and X-940 with a SteppIR DB36. Prior to installing the DB36, I had been using a quarter-wave slope...

How the Phasing System Works A phased vertical system uses two or more antennas spaced apart and fed with controlled phase relationships. When the signals from the antennas combine in space, they reinforce in some directions and cancel in others. The result is...

1. Verticals Work on 160mEven a modest vertical can dramatically outperform compromise antennas on Topband. 2. Bandwidth MattersCombining antennas using tuned 75-Ohm coax can narrow bandwidth more than expected. 3. Stagger Tuning HelpsTuning antennas slightly ...

What began as a simple attempt to replace a sloper turned into a much more interesting Topband project. The phased vertical system is still relatively simple, but it has already transformed my experience on 160 meters. Instead of treating Topband as a place to...
