Hello dear Domenico.

 

The coupling system is very classic :

 

  • At the base of each vertical, the impedance is a= bout 25 =E2=80=93 3400j (including the 25 Ohms of ground rod resistance). I match= that to a 50 Ohms RG58, using a L circuit with a serial 1150 =C2=B5H coil and a 6800 p= F parallel capacitor on the coaxial side.
  • The two coaxial cables have the same length and = are the two inputs coming into the phasing box.
  • The =C2=AB out of phasing =C2=BB box includes a = small single ferrite toroid of Al =3D 700.
    • The primary is 14 turns. The the center is gro= unded and connected to the both ground sides of the two coacials coming from = the antennas. The center of each coaxial is connected to the A and B ends o= f the primary coil.
    • The secondary is 20 turns, isolated from the p= rimary, for 50 Ohms output coaxial going to the band preamplifier ;
      • =
  • The preamplifier is a common 20 dB of gain, high= current type.
  • The Rx is a IC 7200.

 

That is very simple. Of course, it is not a transm= itting antenna, only for receiving ! I test this antenna to see the difference bet= ween it and my K9AY.

Hi , all

Andy,  impressive recepti= on ! Compliments. How the two vertical stylus are coupled ?
Which receiver ar= e you using now ?

Thanks in advance for your replay.
