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.

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

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).

So far I have only been able to compare it with a Tagra BT-101 (The Dancer), the QRM has dropped me from S5 to S1 S2. Good signal reports in DX and reception more than surpassed the Tagra.

I have the antenna installed in the lower part of the tower. Easy to assemble and install and what is in these bands listens to it, the truth works very well. Later I will buy another for the 2nd QTH.

My premiere with the BiQuad-270 sincerely surprised me so much, I had an incredible VHF Pile Up, I took advantage of making a SOTA, 33 QSOs in a short time, Mallorca, Sardinia, Girona etc. very good reports

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.
