Bryan,
Use RG-6 direct burial or equivalent for the beverage connection. No
need to use LMR400.
You should be able to find it relatively inexpensively.
Make sure you have a matching transformer for the beverage impedance to
72 ohms for the RG-6.
W8JI.com will give you just about all the information you need to make a
transformer.

After some more reading... It looks like NE is the best approach. Point it
towards North America. I can probably get it pointed at the lower states.
I wasn't sure if I wanted to go bi-directional or not and try and get Australia
/ NZ but I think I'll go for quiet and just try NA for now.
I will need to take it up about 50-75 feet from the feed point I would guess.
I don't now if an elevated beverage would be a negative.
The ground is mostly hard old volcanic ash with loose dirt here and there..
just enough to make you fall down.... It's usually always dry and I'm
thinking it is a very poor ground.
Drill a few holes for copper ground rods on both side? Put about 10 radial
wires on the rods and spread them around. In Hawaii I'm thinking bailing wire
but it will rust. Fence wire isn't common.
Question.. I was going to start the beverage pretty close to the 40, 80 & 160
dipole in the tree.. I'm low on LMR400. Last of my spool.
If it was important, I could order more from mainland and start it higher on
the mountain - giving me a more horizontal antenna.
Should I be concerned with the beverage distance, using it for receiving and
probably on a different radio?
Thank you.
