[TowerTalk] Dipole Center Insulator

[Patrick Greenlee]

There are some pretty stout insulators available intended for electric 
fence construction.  They are found at places like Orchelns, Atwoods, 
Tractor Supply, and other farm and ranch supply stores. Skip the small 
plastic "egg" type if your dipole is to have much tension and opt for 
the larger stronger plastic ones or the quite stout ceramic units.

There are ceramic insulators with built-in lag bolts.  You can mount 
these back to back with the lags overlapping and weld the lags together 
to get a very stout two hole insulator. These insulators are used for 
stringing overhead electric utility wires and are stout.  Electrical 
supply houses may have these with bolts instead of lags which lets you 
just drill a couple holes in a piece of metal and bolt both insulators 
to it. This gives a stout double hole insulator and is easy to attach a 
lanyard around the bolt if you are wanting to support the center of the 
dipole with a lanyard vice just line tension.
