“Hello Ham Radio Ops,
K5ACL from SignalSearch here with another Antenna comparison/testing video using the Weak Signal Propagation Reporter (WSPR) network.
Testing out an elevated 1/4w vertical vs Link Dipole using a simultaneous WSPR transmitter that was homebrewed by W6LVP – thanks Larry! I’ll run the test on 20 & 40m only (40m using a portion of coil on the Vert. antenna) at 500mW.
The results were a bit surprising since I chose to only use 1 radial on the vertical. I’ve done switching comparisons before, but never a simultaneous one. DXplorer.net (Premium subscription comes with the WSPRlite device from SOTAbeams, but the basic service is free) offers a really neat way to compare antennas with some valuable information.”
