That might have been it, sure.
It had the laterals on hinges around the base that once you got it mounted on the mast,
you pulled them down into horizontal position and tightened down the retaining bolts.
So, imagine me climbing up a 50' pine tree, mast in hand first.... used metal strapping around
the top of that tree (which was CONSTANTLY swaying in the breeze), then going back for the
actual big-assed antenna assembly, climb back up one-handed pretty much, get the j-bolts
on the mast around the antenna mount....
Then I had to extend the mast/antenna up out of the tree enough for the laterals to clear (LOTS
of swaying in the breeze, tree being all spindly up there at the top.
Assemble the antenna, connect the coax, shinny back down enough to finish securing the mast to
the tree, then get down before I broke my fool neck.
Oh, we won't even mention the return climb to adjust the thing for lowest SWR's.

My dad got home from work and I proudly pointed out my handiwork, expecting some sort of praise.
He looks up at it, then slowly shakes his head at me and says "...dang fool..." with a grin.
I was forbidden to ever climb it again once mama found out.
Had to leave the whole thing up there when I moved out on my own a few years later.
I looked on Google Street View recently and the tree is long gone now, cut down some time in the
interim 40 years since.
Anybody else ever use the D104 mic? That thing was the mack daddy of base station microphones.
I remember it cost like $100 back in the latter 70's, which was a ton of money then.
We all monkeyed with them, made them *PING* or "SMACK!* when we keyed them up:
