According to John, AD5RN, there are 3 predominant factors in coaxial cable loss, 1 - Dielectric Loss - power heats the dielectric (try polystyrene dielectric adapters on a 250 Watt, 900 Mhz paging base station - real smoke.., 2 - IR Loss caused by the resistance of the conductors - power heats the cable, and third, Radiation loss where the effectiveness of the shielding is gauged. What goes in, comes out somehow.Now a conjecture on my part - I propose that 100% shielding does not necessarily equal 100% containment of radiated signal (probably pretty close, though).
Will BCC John on this and see what he says, 73, Steve NU5D Adrian wrote: > Isn't coax radiation regarded as a loss? Isn't this radiation depleting the > level of signal found at the source end?
