You often hear recommendations for a ZS6BKW over a G5RV, or even just the opposite. You hear the ZS6BKW doesn't cover 80 meters, but many people use it there with a tuner. The ZS6BKW hits the bands a little closer than the G5RV so you may have to use the tuner more often with the G5RV but how do the gain and patterns compare? I decided to make an animated gif that could compare the antennas on all bands under equal conditions. This graphic doesn't show the SWR but the effect of feedline loss is included in the gain for both antennas. I wanted to see this comparison. I was a little surprised by the results on some bands. Since I went to all the trouble of making this, I decided to share it. Maybe someone else will find it useful. 1. From my perspective it appears that 80, 40, and 30 is a toss-up, although both are poor on 30 meters due to high SWR. 2. 20 meters is interesting. The ZS6BKW has more gain in two of the 6 lobes than the G5RV, but the G5RV has more gain in the other 4 lobes. I would have to give the nod to the G5RV based on better area coverage. 3. On 15 meters both are poor performers due to high SWR and poor patterns, but the G5RV appears to have a small edge. 4. On 17, 12, and 10, I think the ZS6BKW is better, although 12 is a real mess of lobes (10 for each antenna). Jerry, K4SAV Details: 1. G5RV: 102 ft wire, 34.8 ft Wireman 551 ladderline, 80 ft RG-213 2. ZS6BKW; 93.5 ft wire, 40 ft Wireman 551 ladderline, 75 ft RG-213 3. Both over average ground at 40 ft height 4. For 40 and 80 meters the comparison was done at 30 degrees elevation. The take-off angle on those bands is 90 degrees and the gain is higher at 90 degrees. 5. No tuner losses were included in the comparison but with a good tuner this should be negligible. 6. Notice that the outer ring of the plots is set to 8 dBi for all plots. 7. The antenna position relative to the patterns can be visualized as the antenna running horizontally across the center of the plot.
