how much loss on 75ft

[1iwilly]

i know i need to upgrade my coax at the moment I'm using rg-8x low loss double shielded
an amp tech i met said to see how much loss you are getting with the radio only on a dummy load the dead key is 2 watts then i connect the antenna coax to the radio and the meter with dummy load at the end of the ant coax key radio now I'm showing 1 1/2 watts dead key ok not so bad
then i put the amp back in line, so it's the radio amp low pass filter amp set at 200 watts dead key on a dummy load.
took meter again and connected at antenna coax check dead key now I'm showing 150 watts dead key, on 75 feet of the rg8x low loss
my question is how much the loss seems 2% 3% and so on yes i will be switching to lmr 400 but not at this given moment economy kicking my arse LOL

6dB loss is 1s unit on the other side.
There is nothing to fight about IMO.

I am not a big fan of 8x
I have seen a lot of it with the shield oxidized, even turning green after being exposed to weather.

I like 9913 or 9913F if I need a little flex.
It works and I don't have to think about it.

I'm using poor mans version of lmr400 (rg213), it's been up for about 5 years and no issues.

I have a center-fed sloped dipole 14 ft high at the top and two feet off the ground at the bottom 45°s slant, My Radio Shack is 60 ft away..... which cable should I use for 75ft length of coax? the L MR or the rg8x for just the 75 ft run (using a 6 in choke with five turns.) I heard that anything under 100 ft Run that the standard rg8x would be okay to use??? I have an Andy2 with a KL 203 amplifier the Andy2 is set at 1.5 watts output with low swing. swr 1.1and 1.3 any suggestions will help. thank you
