Hey All,
    I think the coax Glen is referring to is FSJ4-50B. This is 1/2" 
superflex cable that has some really good numbers. I recently upgraded 
with this to my bench in the basement. For my two lines to the shack, I 
went with LDF4-50 1/2" hardline. The LDF has about half the loss of the 
FSJ but at the freqs. we are using , you won't notice it at all. Both of 
these almost disappear compared to RG8. The connectors for the LDF are 
about $18 each but installed correctly, you will never have to replace 
your lines again. You can find the loss numbers at the Tessco site. I 
don't work for them, just familiar. I hope this helps someone. 73
