From Reflections III by W2DU: "Second, in the Navy Navigational Satellite (NAVSAT), which is used for precise position indi- cations for ships at sea, the antenna terminal impedance at 150 MHz is 10.5 – j48 ohms, for an SWR of 9.3, reflected power 65%. Also matched at the input to the feed line, the matched-line attenu- ation is 0.25 dB, and the additional loss from SWR is 0.79 dB, for a total system loss of 1.04 dB. This equates to approximately one-sixth of an S unit. This is an insignificant amount of loss for this sit- uation, even in a space environment where power is at a premium."
The title of the chapter is "Too low an SWR can kill you." On Thu, Jul 5, 2018 at 19:08 usmcss <[email protected]> wrote: > Hey Don, thanks a lot buddy!!!
