(4) Assemble the mast sections together (Figure 4). The joiner pieces go into the mast pole ends. Line up the holes, and insert
the 1/4-20 hardware. Tighten until just snug - do not crush the fiberglass. If you are assembling a 24 foot mast, the middle guy
ring must be placed onto the mast end before joining the next piece (Figure 5). The mast pole with the halyard pulley goes on
top.
(5) Place the guy ring on top of the mast, near the pulley (Figure 6). Clip the guy lines onto the guy ring(s). A 12 foot mast
uses 25 foot guys (blue marker). A 24 foot mast uses 25 foot guys (blue marker) for the lower ring, and 50 foot guys (red
marker) for the upper ring. Use 25 foot lines (blue marker) for halyards on end masts. (If you need a center halyard use a
50 foot line for a 24 foot mast, or a 25 foot line for a 12 ft mast. The halyard line will not have a snap hook or color marker.)
Straighten out all lines along the mast, in preparation for standing the mast up. Now is the time to get rid of any tangles.
Attach the coaxial cable to a hard affixed folded dipole at this time.
(6) If you are mounting a folded dipole (BWD/BWDS/BWDI) you must attach the antenna to the mount, and partially unroll
the ends before raising the mast. It is helpful to have an additional person for each antenna end to keep the antenna from tangling.
To hard affix this to the mast, attach the mount to the top mast pole with the supplied clamps. (If you have the ability, you may
find it easier to erect the mast and then attach the antenna/mount to the top after guying.)
(7) When all is ready, raise the mast. You must have people pulling on both the middle and top guy lines to keep the mast straight
while raising. Do not allow the top of the mast to whip when it gets near vertical.. When it is stood up straight tie off the mast
guy lines, and then tighten the nut on the base.
The guy lines must be at a 45 degree angle to the mast, or greater.
If you do not pull the mast up carefully, keeping it straight and supported with all of the guys, you will break it.
(8) Raising the end-fed antenna (AC/ACS/ACI) is quite simple. After unrolling, tie the center halyard line to the insulator that
is preassembled onto the antenna wire. Hoist the antenna to the top with the lanyard.
(9) If you are not hard affixing a folded dipole, it may be pulled up with the center halyard line attached to the top of the
center mount. Clip the halyard lines on the end masts to the rings on the antenna ends. Pull the end lines just enough to snug
the antenna. Do not try to make the antenna wires perfectly straight - you will use too much tension. A little droop is okay.
Retension the mast guy lines at this time if necessary to keep the masts vertical.
