An impressive demonstration

The antenna in operation between the houses of Basel on 40m 
on the 5th.December 2012 in the car
in connection in WINMOR at 09.50h with:
ROME : IK0OXK-5 on  7045    report  5-9 to 5-9+10db
Bern     : HB9XQ-5  on   7047.5  report 5-8
Oslo     : LA3F         on    7048.5   report 5-8
and this middle in the houses as seen here:
 
      

      

      
The radiator on the roof of the car measures 1m x 1m (light fence).
This as demonstration of the efficiency of this antenna,
the

Roomcap 2nd Generation
(Update 3.Jan 2013)
with the following improvements:
- the thick radiating tube disappears
- the bandwidth of the antenna improves
- the radiation efficiency is further improved
- easier to transport
With  measurents on 20m it was concluded,
that the efficiency is over 92 percent!

The principle was remaning the same:
