More info

Materials used to build this antenna have been selected with emphasis on best electrical and mechanical properties and resistance against outside weather conditions.An equally important factor is the durability of these properties in the future.

For the dipole arms a hardened and prestressed copper line with a cross-section of 2,5sqmm and a harder PVC isolation is used.

On the box side of the dipole arm the wire is ended with a wire eye for a M4 screw, made by ZES Dolny Kubin.

Isolated by a shrink tube on both sides. The mechanical connection with the balun is done by a simple wire loop secured with a duplex wire clamp and on the hanging rope side a ceramic isolator, type 16C01 made by MFJ is used, secured also with a duplex wire clamp.

The antenna balun with a ratio of 1:1 and a maximum power rating of 300W PEP SSB is made from a waterproof box of IP56 made by SCAME, model 686.205.

On both sides of the box are screws with closed hook ends, the screws are of size M5, made from anticorrosion steel for long time lasting loads.

A more solidly made SO239 connector is used, with plastic diaelectricum, bolted to the box via anticorrosion steel screws and nuts.

The balun transformer is wound on four ferite toroid cores with the respective measurments of (outer x inner x height) 17,5 x 10,7 x28,5 mm.

The arms of the dipole are electrically conected to the transformer thru a pair of M4 screws and nuts on both sides of the box.

The connector on the antenna serves only to electrically connect with the coaxial cable. For bearing the coaxial cable, use the attached rope. (with inner core made by LANEX).

After the antenna is tuned, it is required to insulate the ends of the arms with shrink tubing to prevent water intrusion.

The warranty does not cover damage made by overloading the balun with more power than specified on the balun`s label.
