160M Vertical Replaced

88ft aluminum tubing vertical.  Top loaded with (4) 22 ft. wires.  Resonance is around 1975 kHz.  A 5 inch diameter coil made of 1/4 in. copper tubing is used in series to bring resonance down to around 1828 kHz.  A shunt coil raises the feedpoint impedance for a 1:1 match and approx. 75 kHz 1.5:1 SWR bandwidth.  There are (96) 80-130ft radials installed.
