A SMALL and GREAT antenna. I wanted something small and easy to carry to my activities on the mountain, weighs nothing. Perfect fit in RX / TX. A great design and success for the activators of SOTA.

The SWR is perfect at 11 m and at 10 m, it goes very well both in reception and transmission. I work QRP with 10 W. they listen to me and I do DX.

The antenna is a gun, compared to another multiband Yagi optimized with many more elements, always superior.

I've been surprised by this antenna (for good), very low noise, very low ROE less than 1.3: 1. Use in 40 m and easy assembly. With 9 W. I have done LU, several EA8, etc. I have made a good change with this antenna, it is installed at 9 m.

It is a wonderful antenna. In the noisy environment I have in the city, before with the vertical, the noise did not go down from S7-8. Now with DX-Quad, depending on the orientation, day, time and band, the noise has dropped between 2 and 5 points. Regarding the ROE, forget about the Tunner, always between 1.1:1 and 1.5:1. In short, an excellent antenna for the people who live in the city.
