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

We called DB and spoke to an engineer. He said that all he could do
was to send us the diagrams for us the make our own. So, I have the
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.

Have you called DB or did "someone" say they don't make the harnesses
any more??? It's been several years since I had any dealings with
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
