Default RG-6 for HF?

I finally got a house out in the woods on five acres and I'm going to set up
a couple of pretty long wires and my Wellbrook ALA-1530. I've pretty much
decided on RG-6 for a couple of 150 ft. runs because the stuff's dirt cheap
and I can pick it up at the local Home Depot. Is the impedance mismatch here
going to be negligible, or should I just bite the bullet and go with RG-8 or
a similar 50 ohm coax?


I would not buy cable with the wrong impedance especially on the
Wellbrook because I don't know how well the amplifier at the head end
stands up to reflections. Some amplifiers become less stable into a load
other than what it was designed for. Why don't you fire off that
question to them.

On the wire antennas you will take a hit on performance depending on
frequency unless you use transformers on both ends.


I'd give it a try. I doubt modern active devices will have any trouble
with such a small difference.
