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
I compare the DL-40 with a Double Bazooka dipole and always better
Compared to an X-50 it has nothing to do
I decided to buy the BIG SIGNAL SkyLoop-4010 antenna and i have exellent results. Very good RX and great TX.
Impressed with this antenna, VHF great and will get to repeaters inaccessible by road irregularities compared to vertical.
I am very happy, it weighs nothing and it takes very little time to mount it.
When I compare with the mobile Sirtel 1200 antenna and Imax 2000 the QRM level is lower and I have more gain.
In UHF works much better than the Diamond X-200 and that BiQuad is 1 meter lower.
