Following are directions for raising the K7UAZ 28-foot fiberglass mast (from Max Gain Systems). In general, please read and following the directions exactly. Virtually all of the techniques, notes warning are based on the real experiences of successfully (and unsuccessfully) putting up this mast about 100 times, refining the process throughout.

b) Place Stake #1 at the end of the measuring rope. Tilt the stake 30 degrees from vertical, away from the Center Stake.
b) Place Stake #1 at the end of the measuring rope. Tilt the stake 30 degrees from vertical, away from the Center Stake.
c) Install Stake #1 into the ground using the hammer. Leave about 1 inch of the stake showing above the ground. Keeping the "T" above the ground will allow you to more easily get your hand under the "T" when you remove the stake.

d) Orient the plastic "T" on the top of the stake at 90 degrees to the measuring rope. This will better capture the guy ropes.

9. Arrange the metal Rope Break adjacent to the whipping, as shown below (need photo). Draw the rope taught against Stake #1. (ADD PHOTO) (NOTE: this ensures the guy rope is just about the right length when you raise the mast. There will be about a foot of slack in each guy rope then the mast is raised. Having only a foot of slack will prevent the mast from falling over!)

13. Uncoil and lay the halyard on the ground it's full length. (NOTE: you want to lay it out its full length so it does not tangle when being raised. If it gets tangled, after you raise the mast the halyard may be above your reach!)

14. Route the halyard through the pulley and tie an overhand knot, joining the two ends. Leave about 8 inches of "tails" in the overhand knot; these tails can be used to attach a wire antenna to the halyard.
