Data from the WSPR web site relating to
monitoring and transmission from VK6YSF Northam Western Australia.
WSPR
Frequency: Dial 1.8366MHz USB (occupied bandwidth 1.8380 -
1.8382 MHz)
Grid location: OF88II
Local Time = +8:00 hours (0:00 =
8:00AM)
RX Only
SSN (Sun Spot Number): 36
Equipment: TS-930 at
5W, Radio computer
interface
Antenna: Antenna#1 Active
Antenna V-1
Antenna#2 Multi-band
dipole with T-Match tuner and 4-1
Current Balun
This exercise was to
compare the compact active antenna with the main station antenna used
for operations on the 160m amateur band.

Conclusion:
The Signal to Noise Ratio appears to
favour the main station dipole over the compact active antenna by approximately
8dB on this band.
