i'm upgrading from the old rg58 coax. I notice htere is an rg8x now that I'm notfamiliar with. Is this comparablr with rg8 and is it as good as rg8? What's the difference between the two ?

I'm sure that their will be more information posted about this but RG8X is a smaller diameter than RG8 but larger than RG58 and is more flexible and to hook up watt meters, indoor general radio jumpers. The quality depends on it having a stranded center conductor and as much shielding as possible. I use the RG8 for outdoor use where it leaves my last switch and runs to the antenna, I would imagine that the RG8 will weather better and maybe have a lower loss.

I use Belden 9913F7. This is the best bang for the buck.
Double shielded and some what flexible. And at 27MZH it is very low loss. Check out Palco Electronics in MI. He has the best deal going, last time I ordered.

Now you've thrown me a curve. RG213? It's for a base setup. Learn something new every day. I do appreciate the info and that's why I asked.

I overkill with: Times Microwave LMR-400 on my PDL-2, and way overkill on my 5/8 GP is Andrews 1/2" Heliax.  |

I'm still happy with 9913F7.
I checked out the loss at 100ft compared to just about anything else. At 27MHZ the loss was minuscule.
But we all have our favorite brands radios etc. 213 and
LMR is great stuff. ;D

Might take a look at "BURYFLEX" or the "COMSCOPE" line of coax .
I have put 1500 watts on RG-8x (140 feet on 10 meters) with no adverse effects and use it or comscope for HF through 440 .

Bladerunner, I just tested 135' of Bury Flex RG-213 with a dummy load and meter. I input 75 watts of FM carrier and got 73 watts out. I have 150' of RG8x and I did the same, 75 watts in and 55 watts out. The small coax is very good, but it does show more loss due to line length than the bigger coax. IMO, 9913 is very good and low loss as well, but you might have moisture problems with it outside, it is like a sponge with all the air insulator inside.

Because this has been a topic on coax, I have a question for those who know more than I (which by the way is nothing) about some rolls of coax that I have here at home.
The one roll is one of those LARGE (1000 ft.) rolls of what is marked TFC-TX10 15 Series, and the other which is a 500 ft roll is marked TFC-T10. What is this coax used for?
My other question would be how do you "test" the impedance of coax? I have some very nice Fluke meters but no knowledge how to test coax to see if it is say 50 ohm, 75 ohm etc...
