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.

DX stations "fall" with an impressive ease, most stations ask about the type of antenna.

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.

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).

The truth is I did not think it would give such a satisfactory result, I receive very distant repeaters, even though the orography is very bad here for the VHF / UHF bands, because we are surrounded by mountains of up to 2,800 meters above sea level.

I compare the DL-40 with a Double Bazooka dipole and always better

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.
