Antenna, 9:1 Transformer and Antenna Tuner
 

To the group:

Has anyone had experience with a random wire antenna hooked up to a 9:1
transformer with lead in wire going to a antenna tuner then to your
receiver? Does the antenna tuner get affected by the inductance of the 9:1
transformer?

I assume by lead in wire, you mean coaxial cable, with the shield grounded
at the antenna?

The 9:1 transformer does not inherently have inductance. If you terminate
the secondary in 450 Ohms resistive, the primary will measure 50 Ohms
resistive.
Perhaps you can better describe your question.

DJB,

First - What Radio / Receiver are you using? Generally with
modern Shortwave Receivers do not need an Antenna Tuner.

Second - Try the using your Antenna with the 9:1 Matching
Transformer and Coax Cable Lead-in-Line connected directly
to your Receiver.

Third - Do you have a good earthen Ground for both your
Antenna and the Equipment in your Shack ?

Fourth - IF you find that you are getting signal overload
or need a better Signal then look for a Pre-Selector like
the MFJ-956 or Grove Mini-Tuner Mini-3.
