I already had my 31′ fiberglass mast that I used to use for SOTA activations. But the bucket of concrete and PVC pipe just weren’t enough to keep it vertical.
In short, I went to Lowes and got a fence pole that is big enough for the mast to slide into. Then I just cut the pole a bit shorter than the mast(when collapsed).
Add in some quikset concrete mix and this thing is not moving. Even here in the Santa Ana Winds.
