I know my answer but was just seeing what other people think about using a coax with extremly low loss. Dont flame me out there is a good bit of theory behind me asking this question.

PS. It is for this reason I Love this kind of site on the web.

I am using 400 feet of tv hardline 75 ohms. App. 50 feet of 50 ohm rg213 at the antenna and the same on the radio side with a 1.1 to a 1.2 swr. My signal on transmit improved and my modulation got louder according to my contacts. My receive did not change that I could tell.I have had rg 213 and rg8 coax app. 450 feet and the tv hard line realy made the difference. All my connections are soldered with hot glue around the center of the coax and a solid wire held with water clamps on the shield. I have been in the radio hobby for about 33 years and I am still learning more things every day. I hope this info helps anyone.
