SECTION 2. TRIPOD INSTALLATION2-32.3 TRIPOD INSTALLATIONCM6 and CM10 tripods are designed to allowinstallation in many types of terrain. Thefollowing installation instructions, however,assume an installation on flat and reasonablylevel ground.1. Prepare the area where the tripod will beinstalled. In most installations, the tripodrequires an area 9 feet (CM6) or 12 feet(CM10) in diameter. Natural vegetation andthe ground surface should be disturbed aslittle as possible, but brush and tall weedsshould be removed.2. Lay the tripod base and mast assemblieson the ground. Apply pipe dope or Teflontape to threads on the crossarm mount(short pipe) and the 1 1/4 inch end of themast. To prevent cross-threading, handthread the crossarm mount into the mast’sbell reducer and then tighten with a pipewrench. Hand thread the mast into thethreaded coupling on the tripod centerbracket and then tighten with a pipe wrench.3. Using a tape measure and a felt-tipped pen,mark the tripod legs to indicate how far theyshould extend. From the end of the 3/4”pipe that attaches to the foot (Figure 2-2),measure up 23” on the CM10, or 26” on theCM6, and mark each leg with a felt tip pen.4. Each leg has a slide collar with a single boltfor loosening or tightening the collar (Figure2-2). Loosen the bolt on each collar with a1/2” wrench.FIGURE 2-2. Extending the Tripod Legs5. Stand the tripod upright and orient it so oneleg points south (Figure 2-3). Extend theleg until the top of the slide collar is evenwith the mark from Step 3 and tighten thebolt. Extend the other legs in the samemanner.6. Plumb the mast by adjusting the south andnortheast facing legs. Loosen the slide-collar bolt on the south facing leg. With thelevel on the south side of the mast, adjustthe leg so the level reads plumb, thentighten the bolt. Repeat the sameprocedure for the northeast facing leg withthe level on the east side of the mast.NOTE: Adjusting the legs can be madeeasier by spraying the slide collar and legwith a silicon spray, and tapping on the legwith a hammer.7. Three rebar stakes are provided forsecuring the tripod to the ground. Drive thestakes through the holes in the feet. Someusers prefer to drive 4 foot “T” posts next toeach leg, and attach the legs to the postswith 2” u-bolts.
