Comet 3D4M Standard Mobile Coax Cable Assemblies can be used with a lip mount or used alone as a permanent hole mount. 

Comet 3D4M mobile mounts come with 12 ft. of low-loss coax with gold-plated UHF connectors. An O-ring is included to help keep moisture from migrating under the threaded nut holding the connector in place. 

Their PL-259 connectors have a removable barrel, so the coax can be routed easily through small holes or tight places without removing the entire connector. They can also be disassembled and reassembled to shorten the length of the coax.
