Default Use of lattice line to feed dipole

I certainly appreciate the comments and advice from you and the other
respondents.

My junk box contains a reel of open wire feeder (#16 solid copper

spaced about every 5 inches), which would run from my Johnson KW
Matchbox to the dipole's center insulator.

I am wondering if I could eliminate a fair amount of aggravation for
myself by using a newer poly-coated window-type ladder line with #14
stranded copper-clad conductors for the feeder.


You'd be in for problems. The windowed (not so)open-wire line is
almost as susceptible to humidity and dirt as twinlead. If you want
to buy open-wire line, get W7FG's 600 Ohms "real ladder line".

If you use the feedline from your junkbox, make sure it doesn't
swing in the wind. Solid copper wire will fatigue (and break) much
sooner than the stranded variety.

Can this type of feeder handle high power?

More power than RG-213 et.al., even more so when unmatched.
