Hi: I have a chance to pickup some RG-149 brand new for almost free. The difference from the specs of RG-213 is that it is 52 Ohm, the rest of the specs that I can find are the same as RG-213. However I found that it says it is low noise. Any one have any info on this RG-149 Coax. 73 De Mike VE3YF http://www.ve3yf.com
