BARRETT<strong>HF</strong> Radio <strong>Communication</strong>s<strong>2018</strong> <strong>Mobile</strong> <strong>magnetic</strong> <strong>loop</strong> <strong>HF</strong> <strong>antenna</strong>ApplicationsDimensions1900 mmBorder PatrolCustomsMilitaryPoliceMining, Oil & GasAid & ReliefPeace KeepingParamilitaryEmergency ServicesConservation780 mmSide view deployedHigh performanceThe <strong>2018</strong> mobile <strong>magnetic</strong> <strong>loop</strong> <strong>HF</strong> <strong>antenna</strong> is significantly moreefficient than any whip-type vehicle <strong>antenna</strong>, producingconsiderably more transmit and receive power. The received signalrelative to whip <strong>antenna</strong> systems varies between +10dB and +14dB. Base <strong>antenna</strong> RF currents in a typical whip system are in theorder of 1.5 Amperes, whereas the <strong>antenna</strong> current in the Barrett<strong>2018</strong> approaches 15 Amperes.The <strong>2018</strong> <strong>antenna</strong> includes a built-in broadband scan amplifierwhich allows it to be used with systems containing Automatic LinkEstablishment (ALE) and multi-frequency networks operating in aselective calling scan group.The radiation pattern of the 2108 <strong>antenna</strong> has low angle nullstoward each side of the vehicle, effectively reducing noise fromadjacent power lines which commonly affect vehicles driving onremote roads that have high voltage distribution lines in closeproximity.All terrain coverage and continuous short range<strong>HF</strong> coverageAs the <strong>2018</strong> predominantly radiates RF energy towards theionosphere it is without doubt the best type of <strong>antenna</strong> for vehicularNVIS (Near Vertical Incidence Sky wave) operations and iseffective in overcoming the skip zone common in whip based<strong>antenna</strong> systems providing superior operation in the range 30 - 150km. For the same reason the <strong>2018</strong> <strong>antenna</strong> is highly effective forcommunication in mountainous areas.Head Office:Barrett <strong>Communication</strong>s Pty LtdP O Box 1214, Bibra Lake WA 6965 AUSTRALIAToll Free Tel: 1800 999 580 Tel: +618 9434 1700 Fax: +618 9418 6757email: information@barrettcommunications.com.auEuropean Office:Barrett Europe Limited, Unit 9, Fulcrum 2, Victory Park,Solent Way, Whiteley,PO15 7FN UNITED KINGDOMTel: +44 1489 880332Fax: +44 1489 565422email: information@barretteurope.co.ukAmericas Office:Barrett <strong>Communication</strong>s USA LLC5770 Croy Road, Suite HMorgan Hill, CA. 95037-9120UNITED STATES OF AMERICATel: +1 408 782 8000Fax: +1 408 778 1683email: information@barrettusa.comNo 149438www.barrettcommunications.com.auBCB<strong>2018</strong>1/2170 mmRugged construction1250 mmEnd view stowedThe <strong>2018</strong> <strong>Mobile</strong> <strong>magnetic</strong> <strong>loop</strong> <strong>HF</strong> <strong>antenna</strong> has been integrated in aroof rack. The ground plane for the <strong>antenna</strong> is a heavy-dutyaluminium mesh floor, which is welded to the frame bars, maximisingcurrent within the radiating <strong>loop</strong>. Using a closed <strong>magnetic</strong> <strong>loop</strong><strong>antenna</strong> design, the <strong>antenna</strong> effectively shields and isolates vehicleignition noise thus providing greater clarity in communications.The roof rack is field proven in some of the world's worst remote areaconditions and is designed to withstand rough corrugated, pot holedand unsealed roads.Mounting hardware sets are available to suit most types of vehicles,including Land Rover Discovery, Toyota Land Cruiser, Toyota Prado,Nissan Patrol and Mitsubishi Pajero. Custom brackets can be madefor all types of military vehicles.SpecificationsFrequency rangePower supply3.9 - 12.5 MHz for the standard size rack12 V - 13.8 V DC (provided from thetransceiver)Supply current 1.5 A peak, 400 mA standbyInput impedance 50 Ù typically with +10 dBmTemperature Operating -30ºC to 60ºCStorage -30ºC to 80ºCHumidity95% non-condensingEnvironmental rating MIL-STD - 810F (immersion).
