I had a Foresar 4 in. diameter 15-27 ft telescoping carbon fiber whisker pole. This pole was stored vertically on the mast. The lower outboard end had a jaw which was secured to a chock on the mast about 1 ft up from the coach top, while the upper inboard end was secured on a car which slides on a 1 ¼ in. aluminum track along the front of the mast. There was a 2nd stabilizing car 2 ft lower which connected to the upper car by a wire and held the upper end of the pole in place when it was stowed on the mast. The inboard end of the pole had a control line. This line ran from the top of the inboard car up to a sheave which swiveled horizontally on the mast just above the mast track then then the line went down around and up through the chock, and attached to the lower stabilizing car which in turn attached to the main inboard car. I used the upper part of this line to pull the inboard end of the pole up the mast and the lower part of this line coming through the chock to pull the inboard end of the pole down.
