Im assuming the reason for the 50% cut in wind load rating when using a lower mast support kit is because of it being clamped to a relatively thin pipe compared to a pate bolted to a tower.
My question is can i increase the wind load rating by using a different method to mount the support kit?
When first set up this pneumatic mast i realized i needed a bushing at the top because the opening is 2 1/2" wide and next to impossible it mount a smaller diameter mast pipe in there straight so i had a pair of aluminum bushings made.
One idea is to turn one end of the bushing down to the kits max mast diameter of 2.063", clamp and weld the kit to my mast bushing then bolt the bushing in the mast collar as usual and mount my rotator and antennas. I was also thinking of leaving the bushing full diameter and using longer bolts to clamp the kit to the bushing plus welding which to me seems like it would be stronger.
Any thoughts on this project would be appreciated.
