[Repeater-Builder] Coax Help

[n7zef]

 Howdy;
 I was given today 2 pieces of mini-hardline marked "Andrews Type 
204909". It is the size of mini-8. I think this is 50 ohm, but what 
would be the velocity factor of it? I want to use it to make lines for 
146.7/146.1 and 443.3/448.3 between radio and cavitys. Putting on the 
ends, does it take anything special, I would like to use solder on type 
id I could.
 Appreciate any help I may get...
