Isn't the Tashjian RLT (Wireless) a remote raising/lowering accessory? It is
on the 2022 price list for almost $3k.

I am with you 100% John. Don't do it. Too many things can go wrong with really
bad consequences.
After a good friend (call sign withheld to protect the guilty) tore off two
runs of LMR-600 and bent up a 3 el 40m full size, the remote was removed from
his UST crank up. Trees grow. Beam heading indicators go bad. The list of
potential cascade failures is not solved by a camera.
There is a reason Tashjian does not sell one and it's not just about liability.
