The antenna has 3 elements on a 20-meter, 3 elements on a 15-meter, and 4 elements on a 10-meter band.
The antenna uses a common feed line. Input power is limited by the feed line only. Very low SWR, excellent F/B. Wind survival speed 150 km/h.
The antenna is assembled and tested before shipping. There is no exception. All our Ham Radio antennas are pre-tuned. Once the antenna is up in the air, you should expect extremely good SWR across the whole designed range, true gain, and F/B as given in the table. You have nothing to tune, nothing to measure. Just put number to number and enjoy the Ham Radio hobby.
