Is the entire PVC run still clean and more importantly, dry?
Do you just want to replace the coax or both the coax and 14-2?
Where are you?  City/State.  In city or out in county?
For a run that long, it is wise to give some thougjt to anticipating and avoiding issues.
Any AC running over that control cable?  Signals only, or power?
Coax size, mfg, #?Existing 14-2 regular ROMEX or direct burial rated?
Lube?  That answer depends on other answers and is a down the road question.

Good morning,

28 years ago I buried a 1.5 inch schedule 40 PVC pipe in the ground and ran some low loss coax and a three wire electrical control cable (14-2 house wiring cable).  The 14-2 is used to operate a remotely control phasing box for my 80 meter four square.  The coax feeds either my 160 vertical or the 80M array.

Well it’s time to replace the coax.  The PVC pipe is 250 feet long and in a straight line(thankfully).  I suspect I will have to pull both cables with the new cables tied to the end.  I’ve never done this before and could use a little advice.  I googled but most of what I found started with empty pipe and ran a “string mouse” through with a shopvac. When I installed the cables initially, I laid them out on the ground and slipped the pipe over them ten feet at a time. Fortunately, there is a fair amount of room left in the pipe.  The two cables did not fill up the space entirely.

My first question is if there is some sort of lubricant I should use to reduce friction?

That’s also my last question, but I know there must be several things to consider I am betting that this group has the answers. I have a come-along, a tractor, and a fair amount of tools.  I’m just not sure how to proceed.

I am eager to see what you all have to say.
