[VHFcontesting] Coax

[David]

I am putting up a 70cm array at 50 ft in the future. I have on hand three 25 
ft sections of Andrew FSJ4-50B coax with connectors attached that was given 
me to me when a local cell tower was moved.  It was used inside and is in 
excellent shape. To use this I would have to use two barrel connectors. 
What would be the loss in the barrel connectors.  Would I be just as well 
off using one section of LMR-400 or the equivalent.

Thanks,
