Logarithmic Periodic Vertical Polarization Half-Power Beam Width

This document summarizes the specifications of an antenna model 742 192. It is a logarithmic periodic antenna that operates within the frequency range of 806-2170 MHz with vertical polarization and a 65 degree half-power beamwidth. Key specifications include a gain of 11-11.5 dBi, an impedance of 50 ohms, a VSWR of less than 1.5, and front-to-back ratios greater than 23 dB. The antenna is designed to withstand environmental conditions up to 60 degrees Celsius, 200 km/h wind speeds, and remain operational in icy conditions.

Special Antennas
For Vertical Polarization

Material: Radiator: Weather-proof aluminum. Reflector screen: Weather-proof


aluminum. Radome: Fiberglass, colour: Grey.
All screws and nuts: Stainless steel.

Mounting: The antenna can be mounted on tubular mast with a diameter of


30 – 70 mm with supplied clamps.

Ice protection: Due to the very sturdy antenna construction and the protection of the
radiating system by the radome, the antenna remains operational even
under icy conditions.

Grounding: All metal parts of the antenna as well as the inner


conductor are DC grounded.
Environmental conditions: Kathrein cellular antennas are designed to operate under the
environmental conditions as described in ETS 300 019-1-4 class 4.1 E.
The antennas exceed this standard with regard to the following items:
– Low temperature: –55 °C
– High temperature (dry): +60 °C

Ice protection: Due to the very sturdy antenna construction and the
protection of the radiating system by the radome, the antenna remains
operational even under icy conditions.

Environmental tests: Kathrein antennas have passed environmental tests as recommended


in ETS 300 019-2-4. The homogenous design of Kathrein’s antenna
families use identical modules and materials. Extensive tests have been
performed on typical samples and modules.

Pressure test: The antenna has passed a pressure test according to Official Journal of
the European Communities L245/171 from 12.09.2002 for the use of the
antenna in train tunnels for high speed railways.
During test the antenna was subject to alternating pressure with a
number of 1x106 alternations of load.
The antenna exceeds the standard as follows:
Pressure difference according to L245/171: 10 kPa
Pressure difference during test: 20 kPa

Please note: As a result of more stringent legal regulations and judgements regarding product liability, we are
obliged to point out certain risks that may arise when products are used under extraordinary operating
conditions.
Subject to alteration.

The mechanical design is based on the environmental conditions as stipulated in ETS 300 019-1-4, which
includes the static mechanical load imposed on an antenna by wind at maximum velocity.
Extraordinary operating conditions, such as heavy icing or exceptional dynamic stress (e.g. strain caused by
oscillating support structures), may result in the breakage of an antenna or even cause it to fall to the ground.
These facts must be considered during the site planning process.

The installation team must be properly qualified and also be familiar with the relevant national safety
936.2134/b

regulations.
The details given in our data sheets have to be followed carefully when installing the antennas and
accessories.
The limits for the coupling torque of RF-connectors, recommended by the connector manufacturers
must be obeyed.

Any previous datasheet issues have now become invalid.
