when using a tram line here i clamp a short (3' or so) pipe to either the boom
boom-mast plate depending on where there is room. this is set so it points up
has a rope tied to the top of it. this way while the tag lines can be used to
control side to side motion this line can be used to tip the elements as the
antenna approaches the tower to clear guy wires. this has worked great for
a 6 ele 20m telrex to 150' and an 8 ele 15m telrex to 120' here. (pictures
available on my web page of antennas, but not tram setup yet)
