Antenna Impedance Matching – Simplified
Standing wave ratio (SWR) is a measure that defines how well the antenna impedance is matched to the connected Tx line impedance. A value less than 1.5 is desirable. A low flat SWR enables maximum power transfer from the ... When a series inductor is connected to the antenna, the combined impedance of the antenna ...

160m/80m Broadband Antenna by K5GP
www.ctdxcc.orgThe SWR plot for an 80 meter broadband dipole is shown below. For the antenna layout below, the center capacitor is 15 pF at element 3 between elements 2 and 4 and a 4:1 balun feeds the antenna between elements 1 and 2. The SWR is less than 1.7 to 1 across the entire 80 meter band. How do we get back the 160 meter resonance? By placing a series

Even antennas that show a perfect 1:1 SWR in mid-band will typically have some larger SWR at the band edges, often due to the reactance of the antenna changing with frequency.
