Slinky Dipole Antenna

Figure 3 Antenna Impedance/SWR Vs Frequency

My balcony is small in sizes thereof the slinky antenna has only two meter length, each slinky vibrator has one meter length. Antenna analyzer showed different plot for antenna impedance/SWR however resonances at 40 and 15 meters band still were present. Figure 5 shows antenna impedance/SWR Vs frequency for balcony slinky antenna. Figure 6 shows fine plot for antenna impedance/SWR Vs frequency for balcony slinky antenna at 40 meter band.

Figure 7 shows fine plot for antenna impedance/SWR Vs frequency for balcony slinky antenna at 15 meter band.

I have been used the antenna for two weeks at the 40 meter band. All QSOs with the antenna were at distance no more the 900 km.

However it is not bad for such small antenna.
