Connectors according to IEC, EIA or DIN. According to customer’s requirements. 87.5 – 108 MHz s < 1.2 throughout the whole frequency range. Lower VSWR for single channels upon request. 50 Ω Horizontal Connectors according to IEC, EIA or DIN are used throughout the system, allowing easy assembly and maintenance. Null fill and beam tilt upon request. Omnidirectional, directional or custom-designed. Upon request, the antenna can be divided into 2 halves (for measurement and maintenance). The 2 halves are connected by a 2-way power splitter or patch panel. Splitters and connecting cables can be supplied with dry air (please specify when ordering). If required, the antenna is painted in aviation warning colours. Via mounting parts. 225 km/h

4 dipoles are arranged symmetrically in front of a reflector screen. With suitable feeding the antenna radiates circularly polarized. An isolation of 40 – 50 dB between horizontal and vertical pairs of dipoles is achieved through the spezial design. This design permits the transmission of 2 programs – horizontally and vertically polarized – independently from each other.
Mounting:
Hot-dip galvanized steel. Weather protection: fiberglass cover.

Max. wind velocity Side-lobe suppression Material:
Hot-dip galvanized steel.
Mounting:
To pipes of 60 – 115 mm diameter by means of mounting clamps, supplied. Attention: Antenna may not be installed with vertical polarization. Special version for vertical polarization upon request.
Grounding:
Via mounting parts.
Combinations:
Several antennas can be combined to increase the gain and to produce radiation patterns with very high side-lobe suppressions.
