Post subject: What is VSWR dB?

In the course of reviewing basic coax cable testing
it was decided to develop a spreadsheet calculator.
A recent find was a table that had the following
columns
|VSWR|VSWR(dB)|RETURN LOSS|TRANS
LOSS|REFL COEF|POWER TRANS%|POWER REFL.%|
I've found equations to relate each column to
the other columns except for column VSWR (dB). It
seems like return loss and transmission (mismatch)
loss account for power loss due to VSWR so I don't
know what this column references. Can anyone provide
an equation and explanation for this column?
Any help is appreciated.

Gings celltron: All of the formulas for
converting between the forms of reporting VSWR can
be found on the following page (there's a calculator
there for you, too).
VSWR - Return Loss
- Gamma Conversions Thanks for
posting.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
