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.

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.

We use a DL-20 on the Radio Club EA4RCH in some international contest. With it We hear very low signals and with much less noise than the Yagi. It's great, very easy to assemble.

Impressed with this antenna, VHF great and will get to repeaters inaccessible by road irregularities compared to vertical.

It is true everything written by colleagues who have opined on this antenna and I just want to emphasize that it is an excellent antenna, with a great behavior in both RX and TX very simple and fast assembly and above all I want to congratulate the Big Signal team for the care with which they treat their products, which are of a great quality. I also want to say that the Your staff's attention is just perfect 73

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

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?
