Data from the WSPR web site relating to
monitoring and transmission from VK6YSF Northam Western Australia.
WSPR
Frequency: Dial 24.9246 MHz USB (occupied bandwidth 24.9260 -
24.9262 MHz)
Grid location: OF88II
Local Time = +8:00 hours (0:00 =
8:00AM)
Transmission Power 33 dBm
(2Watts)
SSN (Sun Spot Number): ?
Equipment: TS-930 at
5W, Radio computer
interface
Antenna:
Doublet Antenna: Multi-band
dipole with T-Match
tuner and 4-1

This exercise was to
compare the Multi-band Doublet Antenna, 40m Sloper Antenna,
10m Sloper Antenna and the L antenna
for operations on the 12m amateur band.
Conclusion is that
there is no compelling performance deference between the Antennas.
