-A- Barrel - Box - Short - Load - Open

 

 

 

 

-B- A New Couple of 100 Ohm Resistors -Roughly Soldered- in Parallel

 

 

 

 

-C- The Barrel in cascade with the Box

 

 

 

 

-D- Impedance Measurements

--------------------------

 

- Black - : The Reference Plane is just before the front Barrel Connector

 

-- Red -- : The Reference Plane is just before the Box Connector

 

 

 

 

-E- Note 1

----------

 

A slight difference between the Black Colored Impedance Curves

and those referenced at:

http://antennas.gr/ax/ax070423.htm

is due to the fact that now a slightly different 50 Ohm DC load was built and measured.

 

- F - Note 2

------------

 

For 50 Ohm VSWR measurements made Just On the Reference Plane of a Discone Antenna Input:
