[TowerTalk] FW: reversible Beverage

[Matt]

Hi Bill,

W0BTU has an excel spreadsheet on his site that will calculate both
differential and common mode impedances for a bi-directional Beverage based
on AWG, height, spacing, and dielectric.

Look towards the bottom of the page.
Hope it helps you out and good luck on your project.

Subject: [TowerTalk] reversible Beverage


A quick question:

I'm considering a reversible Beverage out in KH6 using DX Engineering setup.
Their system requires the Beverage to be constructed of 450 ohm ladder line.
Cost of the ladder line and the cost of shipping 1500 feet to KH6 is quite
high.  The system is designed to operate in a range of 300-600 ohms and of
course the 450 ohms is right in the middle of that range.

I've heard of guys using two wires in parallel to each other spaced 6-12
inches kept apart with home brew spacers and was considering  this as an
economical alternative.  I asked the guy from DX-Engineering if this would
work and he wasn't sure since he didn't know what the impedance would be for
the two wires.  So, here I am.

Any  rough idea as to what the impedence would be for two nr 14 wires spaced
around 6 inches or 12 inches?  I'd really like to use the DX Engineering
stufffor this but want to be sure it would work with something other than
the 450 ohm ladder line.

Thanks ahead of time!
