[. . . ] Thus, for a passive extension antenna, your choices are to limit the cable run, or increase your budget and buy the more expensive, thicker cable.

In the case of low-cost RG-58 cable, adding an SWASS-EXT to your setup increases the acceptable maximum cable run by more than 4 times, to 14 meters. Power for the Extension Antenna is delivered from any Sabine SWM7000 series receiver or SWA6SS Antenna Distribution Amplifier. An additional advantage of using Sabine's SWASS-EXT Extension Antenna stems from its more focused, directional nature. [. . . ] Tighten finger tight only. NOTE: Make sure the rectangular silver shield case (SHIELD-W2ANTL) will face away from the bracket when the component has been remounted. 6 5 Reconnect the antenna component to the metal bracket with the TNC elbow positioned through the cutaway. Tighten the white plastic nut finger tight only. 6 Mount the metal wall-mount bracket to the predetermined location on the wall. NOTE: wall-mounting screws not supplied 7 Replace the wood-grain antenna exterior case. SWASS-EXT-2 INSTRUCTIONS The SWASS-EXT-2 has two features not found on the standard SWASS-EXT: switchable gain and a phantom power LED indicator. The HI/LO switch is easy to see at the lower right of the antenna assembly. Refer to page 3 of this guide for instructions on using the HI gain setting. The Power LED indicates the presence of phantom power from either the SWA6SS distribution amp or an SW70 series receiver. If the LED does not light after you power up the receiver or distribution amp, then you have a bad connection in your RF cabling.

The longer your cable, the more you will reduce the 100meter range between transmitter and receiver antenna. A well-placed pair of extension antennas will eliminate trouble spots and generally improve overall performance of the wireless. COMMON SOURCES OF RF INTERFERENCE The typical sources of interference for conventional wireless mics can be high-powered broadcasters such as radio stations and TV transmitters, or other short-range wireless devices, including multiple radio microphones operating at the same location (either by design, or by coincidence), that operate in proximate (or harmonically related) bands. Less commonly, interference may arise from spurious outputs emitted by electronic equipment (notably computers, printers, or similar devices with digital clocks), faulty electrical equipment, neon signs, dimmers and lighting controllers, and so forth. Many UHF and VHF mics are especially vulnerable because they share the RF spectrum with the very high-powered transmitters for television. The coming conversion to digital and high-definition broadcast will increase the problems for UHF and VHF. Fortunately, Sabine systems are only affected by such ovens in close proximity to receiver antennas. That protection, plus the availability of 70 different RF channels to choose from, makes serious interference problems arising from microwave ovens avoidable and unlikely. Wireless Local Area Networks (WLANS) These computer network devices allow computers to connect via wireless devices that act as both receivers and transmitters. These low-powered transceivers often have selectable channels and can utilize the entire 2. 4 GHz band. In general, Sabine microphones should not be affected by these WLANS because their spread spectrum technology does not present a problem for the Sabine Smart SpectrumTM system. Cordless phones These home telephones broadcast at very low power and should not present interference problems for your Sabine wireless. This is especially true if the telephone uses spread spectrum technology. Wireless Video Cameras Certain wireless video cameras (X10, for example) use the 2. 4 GHz band. These devices are also very low power and, in general, should not present a problem when using the SWM7000 system. See Section 5 Receiver Operation for methods of optimizing clear reception and minimizing interference. See caution below. Antenna Placement Caution As a general precaution, keep 2. 4 GHz cordless telephones, microwave ovens, WLAN antennas and 2. 4 GHz wireless video camera transmitters twice the distance from your Sabine wireless microphone system antennas as that of your Sabine 2. 4 GHz transmitters.
