Topband: Coax as wire for reversible beverage

[Grant Saviers]

Based on poor results (very low rdf) with no messanger RG6 over a barb 
wire fence I built and subsequent modeling that showed this, I think 
another parallel conductor near any Beverage is not a good idea. It was 
easy to support the plain RG6 with PVC pipes tied to posts and I think 
extending the steel fence posts would also be ok, as they are 
perpendicular to the wave prop and a tiny fraction of the wavelength.

A messenger steel wire plus its insulation will also likely have more 
loss and different prop velocity than the braid/foil of the RG6, so 
connecting them together may not work well.  Solid copper conductor RG6 
is advisable given the 160m skin depth for Cu plating over steel of most 
RG6 optimized for 1GHz.
