Messi & Paoloni Is Better Than LMR Coax

Post author By admin
Post date May 4, 2022

Yes, it sure is. Comparing the losses between Messi & Paoloni & LMR Coax cables. The numbers don’t lie in this heated battle between the two coax manufactures. Two will enter, only one will leave in this battle royal. But, you don’t have to take my word for it.
