My 9913f7 has half inch heater hose for about 3 feet at each standoff. Keeps it from flexing too much and weight is taken by the hose and not the coax, and by keeping it off of the ground I never hav
Just received an email from K7FP who is now making an updated tower jack that claims to be the tool for this situation. See the K7FP metalworks page. No connection whatsoever, just got the email one

I don't think there was a boom, at least not on the base, 2 element antenna. If I am remembering the correct antenna it had a spider center with just enough spacing to mount to the last, then 2 sets

I always do mine in alphabetical order, 2 groups. First the 2 larger ones, then the other 6. Never had to remember to write things down. And if I had to splice cable with different colors, no biggy.
