SIRIO AS 100, AS 145, AS 170 mobile antenna Installation Manual
Below you will find brief information for mobile antenna AS 100, mobile antenna AS 145, mobile antenna AS 170. These are CB and 10M mobile antennas with different power and height options, using a 17/7 PH Tapered whip for optimized performance. The antennas are factory tuned but can be adjusted with special rings, nuts, or screws for fine tuning. The AS series antennas are fully designed and manufactured in Italy with coil support made of low dielectric constant plastic like PTFE.

( INSTALLATION AND TUNING INSTRUCTIONS ) INSTALLATION 1) Hole mount installation A) Hole Drilling: Chose the position on your vehicle (centre roof is recommended) and drill a hole according to the mount diameter. Please ensure a good electrical ground contact is made. B) Connections: Position the cable in your vehicle shortening its length according to your needs. Connect the PL259-male to the cable ready for the connection to the transceiver. C) Electrical Tests: Ensure there is no short circuit between the central pin and the nut of the connector. Ensure there is electrical continuity of the cable from the central pin (connector side) to the central contact (antenna side). Ensure there is electrical continuity of the cable from the nut (connector side) to the ground (antenna side) REMARKS: As some antennas are in short circuit and it would be impossible to do the test after the installation, we recommend you test the cable prior to connecting the antenna. D) Installation: Pay attention to securing all screws and nuts during the final installation. E) Suggestion: After the final installation and BEFORE connecting your transceiver, we recommend an electrical continuity check between the nut of the PL259 and the ground of your vehicle. 2) Special mounts installation: Follow the same instructions of Point 1. 3) Magnetic mount installation: Follow the instructions supplied with the magnetic mount. TUNING Most of the antennas are factory tuned and dont need any extra tuning, but in case of fine adjustments we recommend to follow the procedure below: A) To perform a correct test, move to an open space far from metal parts such as metal doors, buildings, towers, gates etc. at minimum 50 metres or more. B) Connect your SWR-meter between the antenna connector and your CB transceiver (follow the instructions of your SWR-meter for the correct use to your equipment). C) The following procedure is used for the tuning of the 40 channels CB-band Radio in the range of: CH-1 = 26.965 MHz to CH-40 = 27.405 MHz with CH-19 = 27.185 MHZz as centre band for EU Frequencies. CH-1 = 27.601 MHz to CH-40 = 27.991 MHz with CH-19 = 27.781 MHz as centre band for UK Frequencies. Select CH-1 on your CB-transceiver and take an SWR measurement, writing down the results. Transmit only for a few seconds because in case the SWR is too high the transceiver could be damaged. D) Repeat the procedure for CH-19 and CH-40 E) If all SWR results are very high (more than 3) probably theres a short circuit in the cable or your antenna is defective. To avoid damages to your CB transceiver DO NOT use it until the problem is rectified. F) If the SWR results are the same on CH-1 and CH-40 and the lower value is on CH-19, your antenna doesnt need any tuning. G) If the SWR result on CH-1 is lower than CH- 40 your antennas electrically TOO LONG and you should slightly cut the radiator by 10mm at a time. Avoid cutting too much. As long as you get the same values on CH-1 as well as CH-40. H) If the SWR result on CH-40 is lower than CH- | your antenna is electrically TOO SHORT and you need to pull out the radiator as long as you get the same values on CH-1 as well as CH-40. REMARK Some antennas can be tuned only by adjusting special rings, nuts or screws so you can follow the above procedure but you don't need to cut or extend the radiator. 9) SIRIO HI-QUALITY ANTENNAS MADE IN ITALY O Copyright SIRIO antenne - Technical Data are subjected to change - Printed in ITALY - Rev. 05/06/2014 - Cod.

Togliere la vernice nella parte interna della carrozzeria per garantire un buon contatto elettrico di massa. B) Collegamenti: Posizionare il cavo dell'antenna accorciandolo in base alle necessita, quindi montare il connettore PL 259 maschio per la connessione all'apparato CB. C) Verifiche elettriche: Assenza di corto circuito tra spina centrale e ghiera di massa del connettore, continuita elettrica del conduttore centrale da un’estremita all'altra del cavo, continuita elettrica calza cavo dalla ghiera lato connettore al contatto di massa lato connettore d'antenna. N.B.: Si consiglia di testare il cavo lasciandolo scollegato dall'antenna poiché alcune antenne sono elettricamente in corto circuito e non € possibile eseguire il test ad installazione completata. D) Installazione: Completare il montaggio dell‘antenna serrando adeguatamente viti e bulloni. E) Consiglio: a montaggio terminato e PRIMA di connettere il trasmettitore, si consiglia di verificare la continuita elettrica tra la ghiera del connettore PL 259 e un punto di massa della carrozzeria. 2) Installazione con attacchi special: seguire la stessa procedura del punto |. 3) Installazione temporanea con basi magnetiche: seguire le istruzioni fornite con la base magnetica ricordandosi che si tratta di un’installazione TEMPORANEA. TARATURA Le antenne sono pre-tarate in fabbrica pertanto nella maggior parte dei casi non necessitano di taratura. In caso si renda necessaria una leggera taratura consigliamo di seguire la procedura riportata di seguito. A) Recarsi in spazio aperto ad almeno 50 metri O piú da oggetti metallici quali cancelli, lampioni, edifici o tralicci. B) Collegare un SWkR-meter (ROS-metro) tra il connettore dell'antenna e il trasmettitore CB. Seguire le istruzioni del ROS-metro рег | corretto utilizzo dell'apparato. C) La seguente procedura si applica per la taratura dei 40 canali omologati per banda CB compresi nel range di frequenza da CH-1 = 26.965 MHz a CH-40 = 27.405 MHz con CH-19 =27.185MHz in centro banda. Selezionare il CH-1 sul trasmettitore CB ed effettuare la misura di SWR annotandone il valore. Trasmettere sempre per pochi secondi perché se I' SWR fosse molto alto si potrebbe danneggiare il trasmettitore. D) Ripetere l'operazione anche per il CH-19 e il CH-40. E) Se tutti e tre i valori di SWR sono molto alti (maggiori del valore 3) o tendenti a infinito, probabilmente e presente un corto circuito nel cablaggio oppure l'antenna € guasta. Per evitare di danneggiare il vostro trasmettitore CB_NON utilizzarlo finché il problema non sara risolto. F) Se i valori di SWR sono uguali per CH-1 e CH- 40 e il valore minimo si ha su CH-19, la vostra antenna non necessita di alcuna taratura. G) Se il valore di SWR € piú basso su CH-1 rispetto a CH-0, la vostra antenna © elettricamente “lunga”, quindi accorciare lo stilo di circa 10mm alla volta fino ad ottenere gli stessi valori di SWR sia su CH-1 che su CH-40. H) Se il valore di SWR € piu basso su CH-40 rispetto a CH-1, la vostra antenna é elettricamente “corta”, quindi allungare lo stilo sfilandolo di 10mm alla volta fino ad ottenere gli stessi valori di SWR sia su CH-1 che su CH-40. NOTA BENE Per alcuni tipi di antenna la modifica della frequenza si ottiene agendo su speciali Anelli, Viti o Ghiere di taratura, pertanto la procedura sopra descritta rimane inalterata ma non occorrera accorciare o allungare lo stilo.
