Yes. The center conductor of 3227 is #10 solid copper, there is a robust 
foil and copper braid, and standard solder-type Amphenol PL259s solder fit 
it quite well. And yes, it is VERY robust cable. 

Someone asked if it is buryable. Another cable in the family, type 3222, 
is a filled cable and is listed in the Commscope catalog as buryable. 3227 
is not. 3222 has the same physical parameters (that is, conductor size and 
shield construction), but greater loss at UHF thanks to the fill material. 
Loss is not specified for either cable below 500 MHz. I've measured 3227 
from 1 MHz to 500 MHz, and its loss matches the published data for LMR400 
within measurement error.
