Default End-feeding dipoles


"Chuck" wrote in message
...
Several authors recommend against end-fed dipoles because of alleged
difficulties in matching to a 50-ohm line. Unfortunately, the "slur" is
dropped without a hint of explanation.

Other authors see it as simple and reliable, and recommend it with
enthusiasm.

A parallel tuned circuit with tapped inductor is usually the recommended
impedance transformer.

In my own experience, matching has always been extremely easy and
trouble-free. So does anyone know why this might be thought so frought
with problems that its general use would be discouraged?

Take a google at "J-Poles" - an end-fed half-wave. (I'm reluctant to call it
a dipole.)
The 2-meter version of the j-pole is used by bunches of folks.
The matching section at the bottom allows hooking it up to 50-ohm cable.
I have not tried it on lower frequencies. But hey - making antennas is fun,
so get hold of an antenna analyzer, and play
eee ha
