[TowerTalk] Director becoming a rotatable dipole

[Timothy A. Holmes (W8TAH)]

Good Morning everyone:

One of the guys in the club here in town has given me the director off 
of an old 10-15-20m beam.  I have not picked it up yet, nor do know the 
manufacturer or model number of the beam it came from, but I was 
wondering what it is going to take to transform it into a Rotatable 
dipole for those three bands.  I am suspecting that I am going to have 
to lengthen it some, so I am guessing that Aluminimum tubing will work, 
this is not a problem, as my father is building an all aluminimum 
aircraft, and working alum. is not a problem.

Your thoughts and comments would be most appreciated
