Hi

I'm anticipating converting my coax fed, ninety foot long, folded
terminated dipole to a ladder line fed folded dipole, without a
terminating resister, fed using an Icom AH-4 antenna coupler. Am I
correct in believing that the best ladder line to use for that purpose
would be the 300 Ohm type to match the nominal impedance of the folded
dipole itself.


Is this a multiband application?
If you want to keep all the wires, I'd make it a fat dipole (rather than
folded).
Why not put the AH4 at the feedpoint and feed with Coax? The box *is* a
bit heavy, but it is weatherproof, and you could run the power/control
wires alongside your coax.
