5/10/2014       My new multiband (40 to 10 meters) non resonant vertical Dipole

ARRL Antenna Book

We realize that an antenna does not need to be resonant to be a good radiator. In fact, there is nothing magic in having a resonant antenna , as long as you have an efficient tuner system    

                                                      

     

10-4-2014   from now I am using one vertical non resonating Dipole on all the bands from 7 to 28 Mhz

   Nice results in dxing on all the bands !!!!!!

 

                          

 

 

1-6-2013   a  second IK4GBU vertical for 12 meters is in operation.........

25-1-2013     after 9 months I reached with this antenna the DXCC 100 30 meters confirmed by LOTW !!!!!!!!!! 

Worked 155.......

This is the IK4GBU - VERTICAL DIPOLE antenna, fixed on a fishing rod.

The RF, coming from the TX, is going up inside the coaxial cable and is using the upper wire with coil as one half of a dipole.

The bottom half of the dipole is done by the outside RF currents on the coaxial shield down to the RF choke and the side coil and wire.

Very simple and effective without charging too much the fishing rod !

Some initial nice long path dx:

 

 

 

 

and from 1971 as DJ0XN:

 

 

 

so I was starting 1964 as I1BIH:
