I wrote an article in the early 80's describing how to use coax, twin 
lead, or any other transmission line to make a Reflection Beverage. I 
had a similar article in Communications Quarterly. The point of both 
was you could use almost any transmission line if impedances of 
transformers were adjusted. Certainly that would apply to coax, 
although you would have to be careful about voltage distribution at 
each end.

I have used 300 ohm twinlead and 450 ohm ladder line with equally 
good results, and coax wouldn't be a problem either.

On 160 meters (or anywhere below UHF) virtually all transmission line 
losses are related only to conductor resistance...not the dielectric. 
Keeping that in mind, any thin small conductor could be both 
electrical and mechanical problems.
