Hi Joe, the link below is for a coax calculator. its self discribatory, it
will let you see the difference the various coax's have agains each other vs
freq. The hight you go in Freq, the lossier the cables are. Two good
barometers are to run comparisons on 2m and 400 mhz. ie. 144, and 432 Mhz,
100ft runs leave the 100 watt input the same and watch the watts out !. that
will give you a really good idea of cable loss. now you can see why I
recommended some RG213 over the RG58 you're running now. you are losing over
50% of your power to the cable loss. that's way to costly for operation
performance. We all cut corners but there are some things not to cut and
running "a good" not necessarily the best feed lines out there is a good
thing to get in the habit of. and a good cable will last you your lifetime
almost. Ok have fun with the calculator.
