1 GENERAL INFORMATION

1.1 General safety instructions

The information that follows, together with local site regulations, must be studied by
personnel concerned with the operation or maintenance of the equipment, to ensure
awareness of potential hazards.

WARNING- RF Power Hazard: High levels of RF power are present in the unit. Exposure to RF or

microwave power can cause burns and may be harmful to health.

Switch off supplies before removing covers or disconnecting any RF cables, and before inspecting
damaged cables or antennas.

Avoid standing in front of high gain antennas (such as a dish) and never look into the open end of
a waveguide or cable where RF power may be present.

Users are strongly recommended to return any equipment that requires RF servicing to Gigawave.

WARNING- GaAs / BeO Hazard: Certain components inside the equipment contain Gallium
Arsenide and Beryllium Oxide that are toxic substances. Whilst safe to handle under normal
circumstances, individual components must not be cut, broken apart, incinerated or chemically
processed. In the case of Beryllium Oxide, a white ceramic material, the principal hazard is from
the dust or fumes which are carcinogenic if ingested, inhaled or entering damaged skin.

Please consult your local authority before disposing of these components.

CAUTION: Tantalum capacitors: When subjected to reverse or excess forward voltage, ripple
current or temperature these components may rupture and could potentially cause personal injury.

CAUTION: This system contains MOS devices. Electro-Static Discharge (ESD) precautions
should be employed to prevent accidental damage.

1.2 Disposal Instructions

All equipment, including batteries where applicable, should NOT be disposed of with household
waste as they are not bio-degradable in landfill sites. They should NOT be incinerated.
For safe disposal take to:
The local (council/authority) environmental waste site, (in Europe in accordance with the

European Environmental directive).

For details contact your local authority/recycling centre.

1.3 Environmental

It is recommended that the rain cover supplied with the equipment is used to protect the unit from
bad weather and pollution when used outdoors.

MTV3- ASUM-7001-07 page 5 of 25

1.4 Health & Safety

Exposure to Non Ionising (RF) Radiation/Safe Working Distances

The safe working distance from a transmitting antenna may be calculated from the
relationship:

D =





in which D = safe working distance (meters)
PT = transmitter or combiner power output (watts)
GR = antenna gain ratio = anti log (gain dBi 10)
w = maximum allowed power density (watts/square meter)

The RF power density value is determined by reference to safety guidelines for exposure of
the human body to non-ionising radiation. It is important to note that the guidelines adopted
differ throughout the world and are from time-to-time re-issued with revised guidelines. For
Gigawave use, a maximum power density limit (w) of 1w/m² is to be applied when calculating
minimum safe working distances.

Important Note: It must be remembered that any transmitting equipment radiating power at
frequencies of 100 KHz and higher, has the potential to produce thermal and athermal effects upon
the human body.

To be safe:

a) Operators should not stand or walk in front of any antenna, nor should they allow anyone

else to do so.

b) Operators should not operate any RF receiver or power amplifier with any of its covers

removed, nor should they allow anyone else to do so.

1.5 Maximum RF Power Density Limits

The RF Radiation Power Density limit figure recommended by Gigawave is based upon guideline
levels published in:

a. IEEE standard C95.1 1999 - IEEE Standard for Safety Levels with respect to Human
Exposure to Radio Frequency Electromagnetic Fields, 3 KHz to 300 GHz.

b. Guidelines for Limiting Exposure to Time-varying Electric, Magnetic & Electromagnetic
Fields (up to 300 GHz) published in 1998 by the Secretariat of the International Commission on
Non-Ionising Radiation Protection (ICNIRP).

Both documents define guideline RF power density limits for "Controlled" and "Uncontrolled"
environments. An uncontrolled environment is defined as one in which the person subjected to the
RF radiation may be unaware of and has no control over the radiation energy received. The
uncontrolled environment conditions can arise, even in the best regulated operations and for this
reason the limits defined for the uncontrolled environment have been assumed for the Gigawave
recommended limit.

Documents a) and b) also show the RF power density guidelines to be frequency dependent.
Different power density / frequency characteristics are presented in the two documents. To avoid
complexity and to avoid areas of uncertainty, Gigawave recommends the use of a single power
density limit across the frequency range 100 KHz to 300 GHz. The 1w/m² power density limit we
recommend satisfies the most stringent of the guidelines published to date.

on payment of a search fee.

2 GENERAL DESCRIPTION

The Gigawave MTV-HD3 mini receiver is designed for all applications, both indoor and outdoor,
where a very small light-weight unit is essential to the operation. The unit features two-way
diversity reception using Maximum Ratio Combining technology

The receiver is available with either DVB-T or ISDB-T demodulation (factory options)

The receiver is comprised of a single miniature unit that contains RF down-converter COFDM
demodulator MPEG decoder and video/audio output circuitry.

This version of the receiver features both MPEG-2 and H264/MPEG-4 decoding with automatic
selection.

In HD mode, in addition to the HD SDI output, the unit provides a down-converted to SD monitoring
quality output at the CVBS port.

Video picture monitoring is available on the full colour front panel LCD screen.

The unit provides 4 audios (2 stereo) with analogue, SDI embedded and AES/EBU digital outputs.

The receiver powers from 10 to 32VDC, and outputs HD SDI, SD SDI and analogue composite
video (CVBS), component YUV and YC, and ASI, Audio outputs are analogue, SDI embedded and
AES/EBU digital audio.

The receiver can be used with a variety of Gigawave antennas:-

 PA series Low profile antennas are used for uplinking ground to air, or on-board linking
 HX series antennas offer increased gain and directivity
 FBA fan-beam antennas offer increased gain and 90 degree sector coverage.
 Parabolic antennas offer the highest gain, and longest operational range

 CO series Omni antennas are typically used for ground based mobile operations, or

helicopter air to ground

Full details are given in the Gigawave Antennas data sheet.

At the transmitting site a range of Gigawave digital transmitters may be used; for example the
complementary MTV-HD2 and D-Cam Clip-On, and MVL-D2 transmitters are available in both
H264 and MPEG-2 versions. Please consult the separate operator’s manuals for information
detailing transmitters.
