[TowerTalk] Stacked 4 El SteppIR's

["Howard Klein" <howk2@hotmail.com>]

Hi John,
Right you are.  I am out of town and forgot the exact boom picture. I know I 
was not very disturbed over the boom specs. I actually got my 2nd 4 el up 
Sunday but before I had time to tune the pair I had to leave town. I can 
only say I am extremmely impressed with the top 4 at 75 ft. The lower at 
40ft (right now) sounds pretty good also. I need to play with the separation 
and tune the individual antennas when I get home to see how the stack will 
work. It's hard to believe that it can only get better. Good <uck to John.
73,
Howard..K2HK

Just put mine up Sunday. The boom tapers from 2.5 inches down to 1 3/4 in at
the ends onlyl Is fine, Plus uses a truss system. Is a BIG antenna too, anad
heavy, 82 lbs. It seems to play just fine. GL, 73 John
