J.P. -
In the spirit of K7LXC's sage advice "do what the manufacturer recommends"
I dug out the Preformed Line Products catalog and here's what it sez:
Nominal Strand Size Recommended Thimble Size
3/16 5/16
1/4 3/8
5/16 7/16
3/8 1/2
"Only heavy duty thimbles are recommended"
3/8" heavy duty open pattern thimbles cost only about 25 cents more than
5/16" thimbles.
A related item from the Preformed catalog:
Regarding "Guy-Grips" (the product typically used by electric, telephone
and cable TV companies for their distribution lines) the Preform catalog
sez:
"Guying of transmission structures and metal towers require Big-Grip
dead ends" ^^^^^^^
Further:
"Big-Grip dead-ends are recommended for use on transmission and antenna
construction."
