PVC for antanna poles???

[Captainlee]

Hi, newbie here

I'm thinking of using a 1 1/4 " pvc sch 40 x 3= 30ft for a dipole with guide wires is this a good idea ???

the pvc will end up sagging

If you're going to use PVC pipe for an antenna or mast, use the thickest walled stuff you can find. You can also think about guying it if it get's very tall at all, PVC just isn't the stiffest thing around and it's affected by sun/heat/wind/etc. Wood would be the same thing, just to a different degree.
Think 'practical', some things just only go so far before they get impractical...

Hey Capt'n,
Anything long enough will bend.

PVC will bend to a point and then break, possibly with sharp edges.
Guying is a must.

I went on the cheap and used a 10' piece of 1-1/4" EMT conduit on the end of the house.


Perhaps you could get threaded steel pipe. Sections can be joined with couplings.

Go to Home Depot or Lowe's or wherever and look in the plumbing and electrical sections.

Don't forget about grounding.

Whatever you do, keep us posted, good luck.

1 1/2 in electrical conduit is far cheaper and far more rigid as a mast. About $8 around here at Home Depot for a 10 ft piece. PCV pipe just gets too floppy after just a few feet in length - IMO. I used a 5 ft piece of schedule 80 on top of the metal masts to isolate the dipole. That worked; but only after I used 'Gorilla Glue' (urethane glue) and inserted a piece of broom handle inside the PVC to keep it rigid.

OK Fellas you have talked me out of that idea,
I like the large threaded pipe idea best.
