ANTENNA ОА 2000V

The OA 2000V Antenna is designed for receiving and transmitting high frequency signals with vertical polarization in the frequency range from 118 MHz to 137 MHz.

The antenna suppresses surface currents and provides high protection against lightning strikes by short circuits of the radiating surfaces on the direct current. The short circuit is provided by a connecting tube placed inside the vibrator. The construction of the antenna allows it to resist high wind forces and mechanical loads and provides a low wind profile. The low weight and small dimensions are additional benefits of the antenna.

ANTENNA ОА 2001V

Aerial ОА 2001V is designed for reception and transmission of HF vertical polarization signal and transmission of HF vertical polarization signal in the frequency range of 100—165 МHz.

The aerial is painted with powder polyether paint RAL 3000 (red as the main color). Subject to the customer’s wishes the color may be changed to RAL 7035 (light grey) or RAL 6003 (khaki). The paint is applied by spraying enamel powder which provides high quality weather-resistant coating.

ANTENNA ОА 2003W

The OA 2003W Antenna is designed for receiving and transmitting high frequency signals with vertical polarization in the frequency range 100 MHz to 400 MHz.

One of the special features of this antenna is its capability to suppress surface currents. The construction of the antenna allows it to endure high wind force and mechanical loads and provides a low wind profile. The low weight and small dimensions are additional features of the antenna. The antenna is painted with polyester powder paint RAL 3000 (red); the color can be changed if needed to paint RAL 7035 (light grey) or RAL 6003 (protective).

ANTENNA ОА 2004V

Aerial ОА 2004V is designed for reception and transmission of HF vertical polarization signal in the frequency range of 118—137 МHz.

The aerial is painted with powder polyether paint RAL 3000 (red as the main color). Subject to the customer’s wishes the color may be changed to RAL 7035 (light grey) or RAL 6003 (khaki). The paint is applied by spraying enamel powder which provides high quality weather-resistant coating.

ANTENNA HK001

HK001 is the all-directional aerial for vertical polarization waves.

Light and solid structure, high resistance to lightning impacts. The aerial cam be used on ships and is ideally suited for air radio communications.

ANTENNA K55

The aluminum vibrator is housed in a glass fiber blister. The steel pedestal is coated with zinc using dip galvanization. Installed using 4 racks.
