GPS Antenna(TIMING 4000) be installed on roof of the building; 2. Cable assembly RG8 fixed along the out wall, one terminator connects TIMING 4000,the another to protector at the appropriate place. In some special environment, select PE or PVC material plastic pipe to protect the cable assembly is quite sensible; 3. Protector, Amplifier and Gain controller are fixed on the wall indoor; 4. Cable assembly KSR240 is fixed along the ceiling of the operating place; Antenna GTA10 be fixed on the ceiling or crossbeam. 6. According to the actual environment, you can adjust positions of some parts, which can make you the adjust, change and overhaul more easily.

Doc.No.1103 Rev.013 2016-08-16 1 Functional Description GT‐RK1 is a repeater operates by receiving GPS satellite signals with an antenna located outside the building and re‐radiating the signals into the indoor area or covered space where satellite signal cannot reach. GT‐RK1 is a single point GPS repeater, one transmitting antenna transmit GPS L1 signal. If need extend the system, you can apply multi‐system receiving antenna and sending antenna, which can support multi‐system, multi‐waveband satellite signal receive and transmit, so as to cover satellite signal indoor. : 或 Other documents, log in website: www.gemsnav.com ,or contact:sales@gemsnav.com, 。...

Doc.No.1103 Rev.013 2016-08-16 6.1 GPS Antenna TIMING 4000 Installation Choose the edge of the barrier, where haven’t construction higher than 3 meters, around the antenna 10ms at radius. 6.1.1 Lighting Protection Usually, outdoor antenna is fixed under the range of building lighting‐protection. If antenna is higher than this area or out of the range, set up lighting rod is wisdom. Lighting rod, installation of attention as below: 1) The height of lightning rod is apply with the position of antenna, much high than antenna(0.5~1m higher and more) 2) Lighting rod wield with the building circuit line, ensure ground resistant less than 10Ω. 3) Can directly wield rough sheet iron to building lightning‐protecting ground.(as shown above) State: Lightning-protection is an important and cautious subject, we only suggest, design and implement lighting-protection must be done by whom was professional and have the qualification authentication.
Doc.No.1103 Rev.013 2016-08-16 6.2Installation to Protector and Gain Controller As Shown at Left: ① Cable assembly: connect to receiving antenna, as Timing 4000,L1A etc; ② Protector; ③ Amplifier:GA40; ④ Connector:NJ‐NJ; ⑤ Gain controller:GA30‐V( not reverse); ⑥ Cable assembly: connect to transmitting antenna, as GAT10,L1P etc. ⑦ Power supply. Fix Gain controller: You can fix according to the 4 hole location. ...
Third: If the below two step were ok, please check the outdoor antenna Timing4000.You can screw the port which connect Timing4000 and cable(carefully screw, not unplug strongly).Notice: when screwing the cable connector, you should make sure to screw the iron pipe, maintain the antenna and cable moveless, which avoid to screw off the cable. After riving, check the voltage between axis of the cable connector and the outer shielding layer to make sure it’s 5V.If no voltage, the circuit has fault, please contact our technical support. If 5V,the antenna Timing4000 can be suspected.(In fact, this case hasn’t appear in our engineering projects.
