Notice the spacing distance on the mast, because it is only 10 feet tall there is no way to stack ideally and use the thrust bearing, so you have to take a little off where you can. I would seriously recommend doing it this way over just sticking the beam at the top of the rotor as it is now unless you want to wake up to disaster. You'll notice that it looks much more sturdy (because it is), and it also doesn't add anything noticeable from the ground. That way when the owner finally does bother you, you can tell him how sturdy it is to belay his fears.<br>

Attached is what I'd do (everything is to scale, estimated on the loops, and adjust the spacing to your liking. You can get the thrust bearing from Stark Electronics in Worchester, Mass for $20 or so. Drive or ship up to you, but I wouldn't do it with out dropping the rotor and using a thrust bearing, similar to Bob's setup and the poll in my back yard that you see so often. <br>

<div><div style="font-family: Arial; font-size: 12pt; color: rgb(0, 0, 0);">I see... it's the same thing I have now for the halos. What was hanging me up, Bob, was I was remembering the beam in my attic in Woodbury and I had to have tons of slack because the antenna was mounted just above the rotor (the rotor was fixed to the attic floor.) Thanks for undoing my mental block.<div>

<div><font size="2" face="Arial">dress the cable from the beam in a straight line domn the mast with wire ties ont he OPPOSING side of the mast from the "rotor stop"......put the LAST wire tie (idealy MORE than one at this point) a foot or two above the rotor. With the antenna turned halfway through rotation (if your "stop is NORTH, then point it SOUTH) bulge the cable out a foot or more so it makes a hump in the same direction the antenna is pointed, then start strpping it to the mast BELOW the rotor at about a foot or two down the mast and continue down with your ties.</font></div>
<div><font size="2" face="Arial">This should allow you enough slack in either direction of rotation.</font></div>

<div style="font-size: 12pt; color: rgb(0, 0, 0); font-family: Arial;">Pictures OR diagrams would be greatly apprecited. No rush, the beam is coming from M2 in California, and I was told it might be about a week.<br></div>
