[TowerTalk] Need ideas for 80m Vertical Foldover Base

[RVZ]

Hi Guys,

Hoping you'll have some ideas on how I can home brew an "Insulated Fold over Base" for an 80-meter Vertical which will be fed at the base and needs to be insulated from ground. Related information: The bottom 32' of the Vertical will be an Aluminum tower. The top 35' of the Vertical will be telescoping aluminum tubing, the combined weight of the Vertical will only be about 40 pounds.  I plan to guy the tower so there won't be much torque on the fold over base.  The tower width is 16-3/4" leg center-to-center at the base and the leg diameter at the base is 1-1/4" so a Rohn 45 tilt-over base would almost work except it wouldn't insulate the tower from ground.   One thought I've had in mind is to purchase solid fibreglass rod that would fit inside the tower legs at the tower base, drill holes through the center of the fibreglass rod, and then anchor bolts through the fibreglass rod to the tower legs on the top and anchor bolts through treated 4"x4"s on the bottom.  But in this case the rod would be a small diameter of aprx. 3/4" so the anchor bolts would be need to be small diameter such as 3/8".  Perhaps a better idea would be to purchase fibreglass tube to fit over the tower legs and then anchor the fibreglass tube to treated 4"x4" at the bottom?   Please let me know if you have any ideas to share on an "Insulated Fold Over Base" for an 80m. Vertical as I'd love to get this operational within a few days for winter DX'ing.     TNX & 73,Dick- K9OM
