Beware of cheap 50 ohm coax

If you suffer from noise you will know that everything you can do to minimize it is a must,using cheap coax with a poor braid can make your noise issues 10 times worst,alot of people don't know that but it's true,even some rg213 coax i've had has been crap,just because it says rg213 on it and it's thick it don't mean it's good,foe me i wouldn't settle for no less then aircell 5 which is 100% shielded,it may cost more but it's well worth it if you suffer from noise.
