Data from the WSPR web site relating to
monitoring and transmission from VK6YSF Northam Western Australia.
WSPR
Frequency: Dial 14.0956 MHz USB (occupied bandwidth 14.0970 -
14.0972 MHz)
Grid location: OF88II
Local Time = +8:00 hours (0:00 =
8:00AM)
Transmission Power 37 dBm (5Watts)
SSN (Sun Spot Number): 33
Equipment: TS-930 at
5W, Radio computer
interface
Antenna:
Doublet Antenna: Multi-band
dipole with T-Match tuner and 4-1
Current Balun
L Antenna: L Antenna
with T-Match tuner
This exercise was to
compare the L antenna with the main station antenna used
for operations on the 20m amateur band.
Conclusion is that
there is no compelling performance deference between the Antennas.
