My perspectives were exceeded, the same brand says it ... BIG SIGNAL. And to the comments of a very active colleague who told me: Luis Mi you are the strongest station you come from the north in your activities. An antenna that by itself with the signals of RX and TX that gives you will surprise you along with low noise (QRM).

The truth is I did not think it would give such a satisfactory result, I receive very distant repeaters, even though the orography is very bad here for the VHF / UHF bands, because we are surrounded by mountains of up to 2,800 meters above sea level.

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.

In the 5 bands the bandwidth is amazing, I use 100 W. And what I like the most is that of: -With what do you get that you get +20 dB?

After trying many verticals, today I work with what for me is the best vertical for 11 meters. The performance far exceeds 5/8. Best of all, the absence of QRM.

I remember the first day I tried it. I was called by a USA station to my activity on a national award from Spain, very happy.

Using the antenna for the SOTA program and only 5 W. of power I have managed to make QSO of up to 170 kilometers in VHF

I hear stations that I had not heard before with the dipole that I also have installed and what I hear I work. I just worked Hawaii (KH7) with a very good signal.
