Default 43mhz antenna help.

You can parallel two lengths of 70 ohm and arrive at 35 ohm impedance.

diagrams. The only thing is that I do not have any 35ohm coax and the
diagram did not show the length of the cable from the "tee" to the
elements. I was really hoping that I would not have to build a
harness. I am really busy right now and do not have the time.

them but then they would make a harness for anything to anything,
just be sitting down when the price comes in...

All he needs to do is get RG-83
RG-83
Z0(W) - 35.0 ohms
Dielectric Type - PE
Capacitance(pF/ft) - 44.0
O.D.(in.) - 0.405
dB/100 ft@400 MHz - 9.0
Vmax(rms) - 2,000
Shield - Braid
