When I compare with the mobile Sirtel 1200 antenna and Imax 2000 the QRM level is lower and I have more gain.

Antena BIG SIGNAL DL-11
The antenna is impressive. I compared it with (Long Wire of 32 meters, Dipole, Vertical etc) and I listen to the stations almost with signal of noise, I put the Quad and surprise, signal of 9 and good radio.

Antenna BIG SIGNAL 2BS-5B
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.

DX stations "fall" with an impressive ease, most stations ask about the type of antenna.

The level of QRM has lowered me a lot compared to a dipole that I also have installed, hears stations that the dipole does not.

I receive VK stations up to 5/9+40db over LP, they give me 9+20 with only 80 W.
