3-Band Antenna:
measured
values
6th. January 2006
Just before
I leave
for 2 months, I measured the 3-Band
antenna for 20m-17m-15m .
Below are the measured SWR values for the antenna
installed
on the car as seen in the picture below.
Values measured with MFJ-269 after 2 m coax cable.
20m:
SWR
14.000 = 1,3
14.040 = 1,2
14.070 = 1,1
14.080 = 1,0
14.260 = 1,0
14.285 = 1,1
14.310 = 1,2
14.340 = 1,3
The SWR bandwidth 1:2 is 13.805 - 14.575
17m
SWR
18.000 = 1,2
18.060 = 1,1
18.085 = 1,0
18.250 = 1,0
18.280 = 1,1
The SWR bandwidth 1:2 is 17.750 - 18.600
15m
SWR
21.000 = 1,5
21.060 = 1,4
21.090 = 1,3
21.120 = 1,2
21.135 = 1,1
21.156 = 1,0
21.220 = 1,0
21.240 = 1,1
21.275 = 1,2
21.315 = 1,3
21.345 = 1,4
21.390 = 1,5
The SWR bandwidth 1:2 is 20.890 - 21.515
This is the 3 band antenna in 20 m setting
