1.5.1 Professional Camera Back Applications – Sports and News

Cobham can supply a range of brackets that enable the Broadcast transmitter to be

connected to professional cameras.

The HDTXBRAC-V bracket for example enables the transmitter to be mounted at right angles

on cameras such as the Thomson 8000 Series, or SONY HD C Series Cameras. The bracket

sits in line on the VLock (IDX style) connector, between the camera and the battery. The

camera is powered as normal from the battery, and battery power is fed to the transmitter

using the cable. The HDTXBRAC-AB bracket is also available with Anton Bauer connectors.

1.5.2 Helicopter Integration for News and Traffic Coverage

Cobham equipment has been integrated in a variety of helicopter types. The Cobham

system integration team can provide advise and integration guidance when installing on

helicopters.

A variety of antennas is available to assist with Aircraft and Helicopter up-linking and down-

linking.

1. Antenna: A variety of rigid, flexi and semi flexi antennas are available from Cobham for

camera mount use.

2. The antenna should be mounted vertically ideally, and exposed to free space.

3. The equipment should not be exposed for any long periods to any form of liquids.

1.5.3 Integration in Vehicles

Users should be aware of the following issues when integrating the equipment into vehicles.

1. Ventilation: The equipment does not require forced air cooling, but ideally should be

mounted to a metal surface for cooling effect.

2. For the additional range required in vehicle applications, the use of amplifiers should be

considered. Cobham offers a range of power amplifiers. Interconnection between the

transmitter and any power amplifier should be kept as short as possible, but where this is

not possible, special attention should be taken to use only low loss cables. An

appropriate cable might be RG213C/U. It is essential to minimise the distance between

the amplifier and the antenna.

3. Long cable runs from the RF output to the antenna should be avoided, for maximum

range.

4. The antenna should be mounted vertically ideally, and exposed to free space.

5. The equipment should be supplied with a clean supply in the range 6V to 17V and

capable of 1.10A maximum at 12V. Care should be taken to avoid direct supply from the

vehicle 12V which can be very noisy. Power conversion will be required for 24V vehicles.

6. The video input can be connected across long video cable lengths so remotely mounted

cameras should pose no problem.

7. The SOLH264TX transmitter equipment should not be exposed for any long periods to

any form of liquids.
