Using the antenna for the SOTA program and only 5 W. of power I have managed to make QSO of up to 170 kilometers in VHF

From the first day I tried it, I was amazed, at first I thought I had put it wrong, there was nothing of QRM.

Antena BIG SIGNAL DL-11
I have used it in QRP / Portable with my Walkie and my FT-817. Easy to assemble and transport. Weighs just. Recommended 100%

Antena BIG SIGNAL BiQuad-370
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.

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

Antenna BIG SIGNAL BiQuad-270
In my QRZ.com you can see the incredible contacts with the Pacific, Middle East and America that the Windom dipole that I also have installed could not even hear. I am very happy with the antenna and of course thank the Big Signal team for your attention.

I remember the first day I tried it. I was called by a USA station to my activity on a national award from Spain, very happy.

Antenna BIG SIGNAL DL-20
Very happy with this antenna, giving me at least 2 "S" more than my Diamond dipole WD-330 in the worst case, many times I listen to DX stations at the QRM level with the dipole and the SkyLine S of 9.
