WHEN I MAKE MY OCCASIONAL CONTRIBUTIONS LONGER I GET

FLAK. WHEN I MAKE THEM SHORT (TERSE) I GET FLAK. MAYBE

I'LL BE ABLE TO LEARN SOMETHING FROM THIS.

ANYWAYS THE BULL DETECTOR FOUND SOME MORE POOP HERE.

AND I HAVE BEEN AWAY ONLY 6 HOURS OR SO.

PLEASE GUYS, IF YOUR GOING TO SUBMIT. BE AS LONG AS YOU

NEED BUT please GET IT RIGHT.

My SWR meter DOES read foward and reflected voltages, and

when used PROPERLY does NOT require that it be used at a

specific point a 1/2 wavelength or integer multiple from

the load. It can be used anywhere along a transmission

line and give me valid readings. If your meter gives

different readings (after allowing for normal line

losses) along a line then there might be rf on the

outside of his coax, or a busted swr meter, or a piece

of bogus test equipment.

IF YOU HAVE BEEN FOLLOWING ALONG THEN THE FOLLOWING HAS

MEANING FOR YOU.

SWR is not really a big issue. If it becomes one go

back to square one of your antenna system design. The

high swr BY ITSELF is not a targeting goal in system

design.

Kudos to LB,W4RNL for his excellent examination of Z

matching. I can tell he is someone to listen to. Worthy

reading material. Right on the money.

THERE NICE AND SHORT. HOPEFULLY NOT TOO TERSE.

IS EVERYONE HAPPY?

ObQrp; If I am putting out 20watts and reflect 15 does

that mean only 5 watts get radiated?

OH YEAH THE EXTRA LINE FEEDS ARE A PROBLEM FOR SOME,
SORRY BUT IT ONLY really ADDS ONE CHARACTER TO THE END
OF A LINE, NOT A FULL LINE WORTH OF CHARACTERS. MY SUBMISSIONS
MIGHT APPEAR LONGER THAN THEY REALLY ARE?
