External power supply 5-20V DC has to be applied using coaxial cable connected to

the input BNC connector, which schematic is shown below.

Warning: Never insert power supply with voltage exceeding operating range o 5-

20V DC! Violation o this operating condition can lead to losing warranty and

destroying the device!

5. Turning on

turning on antenna will turn on automatically upon power insertion

through coaxial cable

turning off to turn o antenna, simply remove coaxial cable or turn o DC

powering component on power source

Warning: Never insert power supply with voltage exceeding operating range o 5-

20V DC! Violation o this operating condition can lead to losing warranty and

destroying the device!

6. Setting of antenna gain in the range -9 to +18 dB

Antenna gain can be set in the range o -9 to +18 dB.

enter settings long (2 seconds) press o UP or DOWN buttons

change settings short press o UP or DOWN button

save settings i no button is pressed during 3 seconds, gain value stops to

lash and actual value is stored in memory

When the antenna is turned on, it will automatically recall last saved gain

settings.

7. Setting of right gain value to get the best performance

To get the best RF per ormance o your wireless system, setting of right value of

antenna gain is important. Allways start with setting the gain, which covers losses o

your coaxial cable. Losses o common types o coaxial cables are in the table on page 8.

I signal indicator on your receiver indicates very weak signal even i you set the

gain which covers coaxial cable losses, you can try to add more gain and get

better per ormance. For example in places with low RF noise this gain can add

multiple working distance o your wireless system.

I signal indicator on your receiver indicates very strong signal and you still have

dropouts in audio, there is possibility your receiver is overloaded. It can cause high

power o wireless transmitter and short distance between transmitter and receiving

antennas. In this case decreasing o antenna gain (even to negative gain) can help

to get much better per ormance o your wireless system.

8. Display settings

Variable display settings are available or possibility to adjust behavior o antenna

display to actual ambient light conditions or speci ic requirements o shooting place.

enter the settings long (2 seconds) press o UP and DOWN buttons at once

change setting short press o UP or DOWN button

save setting i no button is pressed during 3 seconds, display settings stops

to lash and actual value is stored in memory

Available display settings are listed bellow:

b.A automatic display brightness according to ambient light

b.0 display is turned o until one o buttons is pressed, then display

will temporarily turn on or the period o 3 seconds with

automatic brightness settings

b.1 - b.5 manual brightness level set to one o 5 levels (1 is lowest)

When the antenna is turned on, it will automatically recalled lastly saved display

settings.

9. Recommended accessories

Optional accessories include various cables or the connection o the antenna

output signal and input power supply and special threaded variable angle antenna

mounting adaptor.
