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.

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.

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.

I can not believe how well this antenna works both in transmission and reception. I have also compared it with the Diamond X-510 and it has nothing to envy, a super discreet antenna, 100% recommended for portable outputs, SOTA etc ... Without hesitation I recommend this antenna.

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

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.
