[TowerTalk] Conduit ends?

[Paul Ash]

Hello All,

I have been considering running my coax, antenna
selector control cable and rotor control cable through a 3"-4"
inch conduit. I would like to get some opinions on the best
way to handle the ends that are projecting out of the ground.
I did read a former thread that talked about two 90 deg bends
(sounds good for water/rain.) what about bugs/rodents/varmints etc...
Anyone have a good idea how to seal the ends that would still provide 
passage of the cables and could be removed with a minimum of effort
whenever it comes time to replace or add to the cables?

Thanks!
