Data from the WSPR web site relating to
monitoring and transmission from VK6YSF Northam Western Australia.
WSPR
Frequency: Dial 21.0946 MHz USB (occupied bandwidth 21.0960 -
21.0962 MHz)
Grid location: OF88II
Local Time = +8:00 hours (0:00 =
8:00AM)
Transmission Power 37 dBm (5Watts)
SSN (Sun Spot Number): 27
Equipment: TS-930 at
5W, Radio computer
interface
Antenna: Sloper

This exercise was to
compare the 40m Sloper Antenna with the Doublet Antenna and the L antenna
for operations on the 15m amateur band.
Conclusion is that
there is no compelling performance deference between the Antennas.
