Huh? 75 ft of RG-11 has almost 8dB of loss at 146MHz. 75 ft of LMR240 has
9.7dB of loss at 146 MHz.

I won't go through your entire list.

John you need to see where you went wrong. The numbers Jim listed are
either correct or very close. I did not bother to do the calculations, but
looking at a 100 foot chart, the numbers are very close and no where near
the numbers you have.

I thought you may have looked at the web page and missed it defauls to
meters, but that does not seem to be the case to me.
