Both of the SWASS-EXT-3 units allow for optimal placement of external antennas for maximum wireless performance. One SWASS-EXT-3 kit can accommodate up to 70 receiver channels. (See block diagram detail on page 10). ntennA lAcement Extension antennas should be placed in an open area within visual range of the intended transmitter locations. Note that the range of a True Mobility transmitter is about 100 me- ters, but that structural objects can reduce that range. Autions • Since the installation of the antennas influences the operating efficiency of the receiver, the most important rule is to minimize the distance between receiving antenna and transmitter for better reception and performance. Make sure the antennas can “see” the transmitter. • Keep the system away from electrical-noise sources (electric motors, refrigerators, arc welders, etc.). Place the SWM7000/SWM6000 receiver or SWA6SS Antenna Distri- bution Amplifier at least 1.5 meters above floor level. Keep all transmitters at least 3 meters away from a receiver antenna. & c ntennA Abling Able While an extension antenna affords the opportunity to increase the distance from transmit- ter to receiver, there is a loss of signal in the interconnecting cable that limits that distance.
- Page 3 Fortunately, Sabine’s SWASS-EXT-3 Active Extension Antenna offers a far better, more cost-effective solution, due to its built-in active 18 dB signal boost. In the case of low-cost RG-58 cable, adding an SWASS-EXT-3 to your setup increases the acceptable maximum cable run by more than 4 times, to 14 meters. With RG-8 cable, the maximum length is extended to 88 meters! Power for the Extension Antenna is delivered from any Sabine SWM7000/SWM6000 series receiver or SWA6SS Antenna Distribution Amplifier. An additional advantage of using Sabine’s SWASS-EXT-3 Extension Antenna stems from its more focused, directional nature. Sabine receiver’s coaxial dipole antennas (standard equipment that mount directly on the front or rear panels of the receiver or SWA6SS) are more omni directional in nature. In contrast, the Sabine’s Extension Antenna is sensitive to RF reception in a 180-degree arc in front of its mounted position. It extends sensitivity to the front and off-axis side locations as it increases rear RF rejection. The multiple functions (relocation of antenna, boost of signal, directional sensitivity) of Sabine’s Extension Antenna mean there are many applications in which its addition to your system can greatly enhance performance. Here’s a partial list of such applications: 1. Antenna repositioning. Provides solutions when receiver placement options are limited or challenging. Sabine’s Extension Antenna’s multiple mounting options allow higher placement (wall mount or microphone stand mount). 2. Barriers interrupting transmission. Any time a barrier interferes with transmission and reception, Sabine’s SWASS-EXT-3 can be mounted on the transmitter side of the...

Use this LED to verify a good connection from either of these. 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.

Introduction The Sabine SWASS extension antenna is an active antenna. This means it can amplify the RF signal it receives before transmitting it to the cable it is attached to. The reason it has this ability is to make up for the loss in the cable connecting it to the Antenna Distribution Amplifier (ADA) or SWM receiver. For example, RG8 cable has a loss at 2.4 GHz of approximately 7.4dB per 100 feet. Therefore, the correct gain for the SWASS would be 7.4dB for 100 feet of RG8. Although it might seem like a good idea to add even more gain in an attempt to extend the range of the transmitters, don’t do it. It will cause signal clipping in the receiver which will lead to audible artifacts and reduced, not increased range. This document explains how to correctly set the gain pot on the SWASS for optimum range and system performance. Setting the Gain NOTE: You will need to have one of your receivers connected to a PC running the Sabine SWM remote software to perform this procedure. Once you have your antennas installed in their correct positions, follow the procedure below. Turn on all of the transmitters that you will be using with your system. Make sure they are all on different channels. Leave one channel open in the middle of the channel line up for use in the calibration procedure that follows. For example, if you are using channels 1 – 20, skip channel 10. IE, no transmitter on channel 10. LIT-SWASS-EXT-3-OP-080625.indd LIT-SWASS-EXT-3-OP-092508.indd...

Page 8: Installation Cautions
Place the transmitters in the general area where they will be used, IE the stage. Connect one of your receivers to the SWM remote software. Click on the RF Scan button to open the RF scanner. In the scan range boxes, enter the open channel in both the start and stop range. For example, if using channel 10 as shown in step 1 above, enter 10 in the “from” and “to” range boxes. Click the start button to start scanning on channel 10. Go to one of your extension antennas and turn the gain all the way down. Go to the other antenna and turn the gain up until you start seeing Gain pot a red or yellow bar on the RF chart on the channel you are scanning. Now slowly turn the gain down until it just goes away. Go to the other antenna and repeat the same procedure, turning the gain down just until the red/yellow bar disappears. Your extension antennas are now correctly set. InstallatIOn cautIOns Extension Antenna cables — For best results, use high quality coaxial cable with a 50 Ohm impedance. Specifications will vary by cable manufacturer. For best results, use cable with minimal attenuation. The longer your cable, the more you will reduce the 100-meter 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. - Page 9 Your first step in checking for interference should be utilizing the Scan function in the SWM7000 / SWM6000 Remote Control Software. RF scanning will reveal potential RF sources in your location and allow you to make an informed choice of channels to use. The scanner can scan for long periods of time and will give you a report of RF activity over time for each of the channels available on your Smart Spectrum system. See Section 13.4.2.5 RF Scan of the SWM7000 / SWM6000 Operating Guide for more details on RF scanning. 1.
