Tqxin,
Not sure exactly what you're asking.
Coax used for VHF comes in several flavors. For shorter runs (say, under 30' or so total), RG8X is often used. It's about the same diameter as RG58, but has better loss characteristics at VHF frequencies.
For longer runs, it's better to use a coax with lower loss at VHF frequencies. RG8 is the old standard, but there are better ones available, including RG213 and, my favorite, RG214. Even lower loss coax types are available, but are costly and probably overkill for most installations.
Does this help?
