I'm about to place a number of 150' Sched 40 PVC conduits between my shack and new tower. I want to end up with small 200 lb. stength nylon twine in each conduit, then use that small twine to pull th

Gentle turn radius sweeps can be made for 3 or 4 inch diameter PVC DYI using a heat gun (cheap one from Harbor Freight) by heating sand filled PVC conduit. The sand keeps the PVC conduit from collaps

I think this is all great advice - I'd add a bit more Use pull tape or braided rope so you don't put twist into the cables when being pulled. Pull tape comes in various sizes and strengths, something

Very important...How long is this run and how deep. Snow won't hurt, it's just a nuisance. IF the conduit maintains a grade all the way it won't fill up with water and freeze. This part I'm afraid to
<snip> And here you hit it on the head. In most places (assuming you installed the conduit correctly) it's not leakage that gets the water in there, it's condensation. As the atmospheric pressure cha
I used silicon caulk to join my conduit. It's waterproif and you can break the seal in the future if needed. Ryan K3XC _______________________________________________ ________________________________

burying conduit vs pulling when (STEPHEN L SALA) Steve, What is the make and part # of the cable ? What OD is the cable ? What is the ID of the conduit ? What type of bends (angle) ? Without knowing
Thanks to all who offered advice. Executive summary: Pulling the two 1/2" runs of hardline/heliax through 265' of 4" conduit was much easier than expected. In fact, it was so easy and went so fast th
Without quoting back the whole thread, here's what I've done so far. The tape goes in about 3 feet or so and just stops quite suddenly. I'm using greenlee fish tape, very solid steel and about 1/8" w

I'm an ex linesman. We used to do runs of 3 conductor lead sheathed 500mcm (about 1 inch) cables. Distances were usually 500 to 750 feet. My thoughts on this..... Run TWO conduits. You say that you'l

Yes I go up to 75%, but "use lots of WIRE SOAP" http://www.rogerhalstead.com/ham_files/cablebox.htm and use a messenger of sufficient size. Far too often messenger cables are too small and can exert
Back in 1997, I installed a set of three conduits, 4", 2.5" and 1", running 265' down a fairly steep hill to a crankup tower and some other antennas. The 4" conduit contains two coax runs (it was ori

I am amazed at the number of hams who don't understand basic physics. First of all, condensation requires a supply of air with a dew point above the temperature inside the conduit. The total amount o

Previously I mentioned here that I wanted to use 3/4 inch ID black plastic drip irrigation tubing rated for 100 PSI and available for about $12 per 100 ft roll at the big box stores like Lowes or Hom
