o donQt need to do calclation for VSWR4

+he otpt Dmeasred VSWRD is already VSWR %ale in nit =42

Hi& 7arim and all

*irst& the script otpt is misleading4

+he second last colmn is already the actal VSWR& there is no need to doany

,t means the last colmn is not correct and shold be remo%ed44

Second& abot the threshold setting4

We can ha%e measred VSWR less than 249 for most MCRRHs& bt 'e canQtgarantee

5specially for some modles 7arim mentioned& e%en if 'e chec( theconnection& VSWR

Which design is better MCRRH .== is ! or 3K

is MC-RRH !2== ha%e same design of MC-RRH .== 3K

Why no isses for 6!2==K

Any benefits of this designK

+he AR text says

High rate of VSWR alarms that can be fixed only by MC-RRH replacement

And alarms are Dcleared only by replacing the MC-RRHD4

0oes this mean#

D the RRH 'or(ed 87& then >'ith nchanged VSWR settings@ later startedto generate

alarms

D the RRH 'or(ed 87& then >at the time the VSWR settings 'ere adJstedto 249-24"@

started to generate alarms

0o yo interpret this to imply#

D the RRH degrades in operationK

D the ne' RRH has a better accracy than the replaced RRH
