1. GeneralThis specification covers 2kW FM Vertical dipole antenna system. The antenna system

consists of 8 Vertical dipole antennas, 1/2" branch feeder, power divider, 1-5/8" main feederand accessories.

2. CharacteristicsThe characteristics of products are shown in attached sheets.

2-1. Eight(8) stacked V dipole antenna systemElectrical and mechanical characteristics are shown in this design sheet.

2-2. Diagram of the systemThe feeding diagram of 8 stacked 1 face antenna system is shown in the attached sheet.

2-3. Antenna mounting hardwareAttached drawing is for reference. The parts of the mounting hardware is fitted to the diameterof actual installation pole or the member of mounting tower.

2-4. Horizontal radiation patternAttached radiation pattern is for reference. Actual radiation pattern of the rear is effectedby the mounting pole and member of the tower.

2-5. Vertical radiation patternFeeding power of each antenna is even, and null-fill-in level at the first null point is more than 10%.

2-6. V Dipole antenna unitElectrical and mechanical characteristics of the unit antenna are shown in attached sheet.

2-7. Main feederThe characteristics of main feeder and accessories are shown in the catalogue(CAT NO.T302B).

2. Details of supplySupply item are shown in table 1.
