They will outperform dipoles when it comes to long distance contacts and even compare favourably with beams located 10m or more above ground. Unlike other verticals you don’t need long wire radials. With these you get adjustable rigid radials that are self supporting, and a DC return in the base matching unit helps the antenna get rid of static noise which other models suffer from. You can adjust the antennas for each band, something you will have to do on 80m as the bandwidth is quite narrow.
