In UHF works much better than the Diamond X-200 and that BiQuad is 1 meter lower.

Antena BIG SIGNAL BiQuad-270
A great antenna in RX and TX. The QRM noise has dropped me to signal 4-5 and with a Bazooka dipole I have 8-9. I give an outstanding, thank you very much now I enjoy the 40 meters again.

Antenna BIG SIGNAL DL-40
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.

Yesterday I finally tried it, I made more than 100 QSOs with Europe and then in the evening, South America and North America. Comparisons with a Yagi mono band of 6 elements, always the Quad is superior.

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.

Compared to an X-50 it has nothing to do

The SWR is perfect, the antenna is a gun and works better than my yagui with more elements.
