Building a Mounting Pole or Mast
CAUTION: TALL POLES AND MASTS CAN BE HEAVY AND POTENTIALLY
DANGEROUS. USE EXTREME CAUTION WHEN CONSTRUCTING OR WORKING
AROUND TALL POLES AND MASTS. BIRD-X, INC., ASSUMES NO RESPONSIBILITY
FOR DAMAGES OR INJURIES.
Things to consider:
•
The 20-Speaker Tower is designed to mount onto a 1 in. (outside diameter) pipe at least 14 in. long. 1 in.
conduit works well as it is light, rigid, inexpensive and available in 10 ft. lengths making it ideal for low areas,
vineyards and bushes.
•
You will want to take down your Mega Blaster PRO unit after harvest and store it in a dry location until the
next season.
A suggestion for masts up to 20 feet tall:
1. 3/4 inch Galvanized steel water pipe has a 1 inch outside diameter and is the correct size to fit inside the
20-Speaker Tower. It is often available in 20 ft. lengths from hardware and plumbing supply stores. If
these are not available, 10 ft. lengths are common and can be fastened together with a threaded coupler.
Assemble the poles on the ground.
2. Slide the 20-Speaker Tower over the pipe and tighten the set screw in the collar at the base.
3. Stand the pole assembly up just inside the drip line of a tree and securely tie the pole to a few heavy
branches.
4. Drive a T-Post into the ground at the base of the pole and secure with wire.
For masts taller than 20 feet:
1. Use 20 ft. lengths of galvanized steel water pipe or similar, securely fastened together with threaded
reducing couplers.
2. Starting with 3 in. pipe, step the size down with each length of pipe.
3. The last 10 ft. can be 1 in. (O.D.) conduit hose clamped to the final section of galvanized pipe.
A semi-permanent mast support can be made by digging a hole 4 ft. deep and 4 ft. round. In the middle of the
hole sink a length of galvanized water pipe large enough that your mast will easily fit inside. Make sure at least
2 ft. of pipe is above ground level. Fill the area around the pipe with packed sand, leaving the last foot filled
with concrete to form a cap over the hole. Your mast can be droppe
d into the galvanized water pipe “receiver”
for support. At the end of harvest the mast can be lifted out and positioned on the ground for easy
disassembly and storage.
