80 meter ham stick on a single mag mount

I added two radials sixty five feet long and had a totally usable 80 meter band for a General Class License.  This five pound single mag mount is only used when stationary.  Without the two radials the swr was all above three with radials the swr was all below two point five.

Above is a scan in process on SWR not the individual frequency SWRs.

This is the roof of our tow vehicle a Chevy spark.  When I took off the radials the SWR went off the chart.  I also found I still could use most frequencies with only one radial.
