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

The antennas was up from the trees about 3- 4 meters from the ground and i was receiving 5/9+ signals. It was incredible when i was on air as C91GBA, great performances with a simple station, FT-857 with 80 W.

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.

When I turned on the radio I was amazed. QRM practically null compared to the vertical I had which gave me S8 S9 of noise and now it does not reach S3. Everything you listen is worked.

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.

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 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.
