[TowerTalk] 75 ohm - v - 50 ohm coax

[TexasRF at aol.com]

The vswr on the coax is 75/50 with a perfect 50R load. Measuring with a 50  
ohm vswr meter will show vswr from 1:1 to 2.25:1 depending on the line  
length.

If the antenna has an impedance of  50 Ohms, and the coax is close to a 
quarter-wave or odd multiple long,  you'll see an SWR(50) of 2.25:1 at 
the shack end instead of  1:1.

##  I thought it would be just  75/50 =  1.5:1
