I need to put together a dipole for Saturday morning. Doesn't have to last long  What is the easiest/quickiest way to construct the center insulator?  I figure a Dogbone insulator and some electrical tape. Any favorite ideas for an expedient dipole?

Piece of PVC pipe?

Small section of hardwood?

any double ended insulator.

I always keeps a handful of insulators and center insulators on hand, never know when I'm going to want to toss up a new antenna.

Plastic holder for a six-pack of beer cans.  Old Field Day standby.

Tie the wires and the coax to the plastic ring with enough extra length to connect them.
Tie a rope to it to hoist it up.  Presto, you're done.

I would fold them up so all six holes are together for added strength, but you could even
cut them apart if you were building multiple antennas and were short on beer.

You could, of course, do the same thing with a slice of large diameter PVC or ABS pipe,
or a shower curtain ring, or a loop of baling twine, or punch some holes in a plastic jar
lid, or use a short piece of broken garden hose, a large grommet, or cut one from a
plastic milk jug.  I've made a lot of insulators from a broken chunk of PVC privacy
lattice, my portable dipole kit has used a slice of radiator hose for 30 years, and I've
even used sticks and a piece of leather when I couldn't find anything else handy.

Fencer insulator, the kind with the little tension axle in the middle & hole on each end. Get a bag of 'em for next to nuthin' at the CO-OP or farm supply store.

Divining an insulator is an exercise only limited by your imagination. Turn a kid loose on that thought & see what happens. Wink

Plastic coat hanger has worked for us on a few temporary dipoles and the hook made for a nice tie off place.
