FWIW - Here at VY2ZM - I am running RG6 (standard stuff) out 3500 feet to a 
distant RX antenna on the other side of my property.


I am also switching 12VDC down the line (using a BIAS Tee) - in order to switch 
the hybrid coupler from NE to SW - All of this is on 160M - so I think you will 
surely be OKAY with only 1500 feet of BELDEN RG6 at 160m.

The copper clad steel center conductor won't make much difference in terms of 
loss on 160m. It is an issue if you will be powering Anything through the coax 
(like amps or antenna selection relays) since the dc resistance is higher. 

If you need solid copper center conductor rg6 you can get that too - its sold 
for satellite systems that run dc on the coax to power the LNB at the dish. It 
will generally be more expensive. Solid copper center conductor will be listed 
as type BC (bare copper) in the datasheets.
