MES 334011 YN series high performance Yagi Antennas features high gain and is ideally suited for directional applications operating in TETRA 340~400 MHz frequency band. The unique design of this Antenna allows it to be installed for either vertical or horizontal polarization.

MES 33408 ODN series high performance 8.0 dBi Omni Directional Antennas are specially designed for TETRA applications in 340~400 MHz frequency band. Heavy duty fiberglass radome is durable enough to stand up to over 60 msec wind loads. All metal parts in the antenna are DC-grounded to reduce the noise caused by atmospherical discharge. No frequency adjustment is required. Mounting is easy with two extruded aluminum Ubolts which secure the antenna firmly to mast.

MES Lightning Protectors are coaxial devices using N Female connection interfaces. These can operate at current and future wireless communication bands (2G, 3G�) Maximum VSWR is less than 1.20 in the working frequency band. Our Lightning Protectors are silver plated with a Non-Magnetic BBR* over-plating to provide protection against corrosion. (*BBR is a non-magnetic material which provides a superior non-tarnishing surface). Our Lightning Protectors have dust and water protection complying IP67 for indoor and outdoor applications. These are reversible and can be used in either directions. These have been successfully tested under vibration, salt spray and thermal shock conditions.

Features : May pass low residual voltage of less than 15 volt s • Do not pass DC signals and thus incorporate a long stub element

MES 4000 series compact Preselectors are typically extruded Aluminum four cavity bandpass filters using Multi window configuration to realise high selectivity. These are used when additional filtering is required in receive path, typically in congested RF environment. It minimises out of band interference. The Preselectors are compact and offer stable response over extreme operating temperature range. Custom built Preselectors are designed in addition to industry standard designs.

Features : Low Insertion Loss • Low Ripple in Pass Bandwidth • High Selectivity

MES 64927 SDN series Parabolic Dish Antennas provide coverage in ISM band of 4900-5000 MHz frequencies with a VSWR performance of less than 1.5:1.These are suitable for long range operation and can be configured for either horizontal or vertical polarization. The reflector dish of these antennas is constructed from high quality aluminum which gives them superior strength. The dish is coated in a light gray UV-inhibited polymer for durability and aesthetics.

MES 3800100DC X series Broadband100 Watts Directional Couplers are designed to decouple a defined part of the RF signal off the main through line. This permits signal distribution of Wireless Systems with the required Signal strength. A Coupler consists of a pair of strip lines approximately a Quarter wavelength long configured to provide the desired coupling These are used in GSM, CDMA Indoor Distribution System WCDMA BAse Stations, Repeaters etc.

Operating in UHF band, it provides interference free wireless data network to existing mobile users having voice transceivers preinstalled in their vehicles. The unit is compact, light weight, rugged and adapted for harsh mobile environment. It underwent rigorous field trials including operation check at 70°C. 215 units are already supplied to an Australian company.
