G4ZU JUNGLE JOB

Processing " JUNGLE JOB " antenna is very easy and quick install in gardeen house. Check details very well the distance between the differents parts as the synoptic below and you can enjoy an antenna system with 5Decibels Gain improved. Just 1 point on Smeter.

G4ZU is a antenna with copyrights trade  but you can build yourself for you and free. This system is composed by a system dipole  coupled reflector V (improves gain with small directivity)  With coaxial cable, the balun  is necessary and if the length is adapted.

In differents sources internet, you can find G4ZU system as different built positions. but always as the portable system antenna. In some cases bibliography, G4ZU is composed by a horizontal dipole and the second element is just the reflector in V. It was this variation antenna  process that i have experimented in built at house. 

In some books antennas, "G4ZU Jungle Job" antenna can be more complex, with a third element (reflector in V, dipole ray, director in V) as the "Spiderbeam" antenna trade... It's only a monoband system transmit  (including balun+coax)
Or directly coax+gamma match (if the dipole is aluminium 😋)

7X5QB 7X2VFK 7X2ARA

Contacter la station 7X2ARA lors d'un contest!! Et j'ai eu la superbe surprise de recevoir la carte officielle en échange de la mienne via le bureau. Cette superbe carte  est mon premier contact   avec l'Algérie.  Je remercie la gentillesse de l'opérateur qui a bien voulu m'insérer dans  sa pile-up lors du contest! Il n'y était absolument pas obligé. 73s de KRIS F4GHW

Par la suite d'autres contacts avec les OMs Algériens mais c'est devenu plus technique au niveau radio et je n'étais pas trop confronté à de tels échanges (QRP ou avec directivité des antennes?)

J'ai tant bien cherché à comprendre mes écoutes et QSO au cours des jours suivants. Voici les détails des moments.

Contacting Algeria station 7X5QB on 10 meters QRP. How it was possible a RST 59  Moscou and  France  rst 412 ! Probably my station was in a silent zone, and not possible to listen 7X5QB. It was my first time to be in this situation as listener. So the 2 ways QSO was been possible the afternoon on 20 meters only. 

19 october, 2 ways radio with Algeria Club Station 7X2VFK on 14200 Hertz was not easy! What is the problem with Algéria ! Huum Huuum ! Just 1000Km by radiotransmit is not difficult on 20 meters?  ... QSL efectively but very hard with QRM  on 14.200MHz. Strange situation to be in the silent zone receipt !

PLEASE take a moment about this article :
