Be Sure to First select a location that lends itself to applying a Load without Compromising the Integrity of the Material you afix to. Further, Think about what's underneath the exterior. Is it stronger, will it yield to Pressure over time as well? Next consider the Location over a Lifetime of Adjustments, does it lend itself to modifications in Height or Direction? Larger Antennas increase the surface area presented to air movement, Hence, Wind-load does increase.
As the length of the mast increases from Its last attached point on the structure, the torque applied also increases with Weight and Wind-Load, requiring a more substantive attachment and Load-Bearing material.

Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Cut each length of conduit in half to make 5 foot sections. Five feet sections fit nicely in the trunk of my car. Adjust the dimensions to suit your needs. PVC conduit has one flared end which works well for this project.
The flared end should be at the bottom of each section in order to keep water out of the mast in wet weather. The very bottom section is made from a piece of PVC with no flare.
The total length of this mast is 20 feet. It could be made taller by cementing a PVC coupling or matching threaded ends. If you go taller you may wish to add another set of eye bolts and guy ropes.
Self Supporting Antenna Towers
Measure up about 18 inches from the flared end of one section and drill 3 holes through the center of this section. Space the holes about an inch apart and rotate the conduit with each hole so the eye bolts will be approximately degrees apart measure the circumference and divide by 3. Insert the eye bolts and tighten the nuts. I plan to run coax up through the center of the conduit so I also cut a slot in the bottom of the base section where the coax will exit.
This would also be a good time to number each section. The top 3 sections each have one flared end. The top section being number 1. The second sectionwith the eye bolts, number 2. The third section with a flared end, number 3. The bottom section with no flared end, number 4. You'll want to keep the base of the mast from moving. I expect to use my portable mast primarily in grassy areas so I've chosen to use a timber spike and a PVC cap to hold the bottom of the mast firmly in place.
Drill a half inch hole through the end cap. Choose where you want the mast to stand and push or pound the spike into the ground through the cap.
The anchors should be approximately degrees apart and about 15 feet from the base. Start from the base and walk off the distance to each anchor location and screw it into the ground.
Tie a tautline hitch with the loose end of each rope to each of the anchors. The tautline hitch is a knot that will allow you to make adjustments in each guy rope to hold the mast perfectly vertical.
I made this simple antenna for the amateur radio 2 meter band and afixed it to an end cap.This vehicle mounted antenna mast is designed to be installed by the customer on a van, cargo trailer, motor home, or other suitable vehicle.
