40m ECOCFD Antenna, VERSION 2

Feedpoint Split: 19% / 81%

Version 2.0-UN

ALL versions of Ver.2.0 were made with the 4:1 Ruthroff 19% from the end with the 1:1 Guanella.   It uses the exact same two baluns and coax/wire as Version 1.  Only the position of the feedpoint has changed.  The 4:1 Ruthroff for this and future versions are configured as an UNUN.

Version 2.0 keeps the same length as Ver.1.1 and Ver.1.2, but has its feedpoint is 1% closer to the Guanella choke-balun. 

COMMENTS:

There was quite a bit of change.  It is best seen in the graphs comparing Ver.2.0 to Ver.1.1 below.
