Just for clarification about LMR900:
There absolutely is a coaxial cable called LMR900 made by Times Microwave  
and sold through their distributors. It is a low loss and quality cable with 
 performance approaching that of 7/8" Heliax type cables.
There is not a product offered called LMR900U. 

##  per Joe at  Times Microwave.   They actually did make LMR-900-UF
but the demand for it was not there, so it  was discontinued asap.  It 
either was never sold at all... or was only in circulation for a very short
period of time. 900-UF is STILL  listed on their power/attenuator
drop down box of various cables.  It's still listed on various Wye-fi
commercial group sites. 

##  TOO bad, cuz it would be a superb cable.  The UF  versions
are super flexible,and much easier to install.  I use 1200-DB,
and it's  no fun to install it !   900-DB is just as bad. 

##  900-UF  would be an ideal cable, for going up the side of a 
crank up. Lower loss than 600-UF.   They missed the boat on this one.
They should have made it avaialable,  even if it meant fewer 
productions runs  per year.  There is still a market for it. 

## a lot of folks would use 900-UF  vs 1200-DB... simply based 
on faster/easier install in a  lot of  commercial /ham applications....
 even though 1200-DB has lower loss. 

Later.... Jim   VE7RF   

Cables sized from LMR600 and lower are available in the standard or the "U" 
 version. The U designator implies a stranded center conductor allowing 
more  flexibility as well as repeated flexing as in a rotor loop or crank up 
tower  service.
It is extremely unusual to see an amateur installation using a size larger  
than LMR600.
