ANTENNA-1: CLASSICAL DIPOLE

( Inverted-V Configuration )

 

Pictured here is ANT-1-B0

 

This antenna is a very simple, relatively lightweight dipole.   Weight:  312 gr.

 

Note that I have clearly marked the leg that is attached to the center conductor of the coax.

This is to enable comparing the amount of common mode current into a diagonally run length of coax, dependent on orientation of the legs.  I will measure once, then rotate the antenna 180 degrees and measure again.

 

In further tests, I will add different types of baluns or chokes to this antenna and repeat the tests.

ANTENNA-1-B1

 

ANT-1-B1 is a simple dipole, identical to ANT-1-B0, except it has a 1:1 Guanella balun at the feedpoint.

 

It was mounted on the same pole at the same height and used the same coax, etc.

ANTENNA-1-C1

 

ANT-1-C1 was made using ANT-1-B0 (no balun) and then connecting RF-Choke "C1" directly to the feedpoing.  "C1" is a 1:1 current choke using a Maxwell design.

 

C1 is described in the section on "Components", under "Chokes".
