(see chart on page 19). t rompeter design engineers understand the unique problems associated with the combination of high data rate digital traffic and high frequency transmissions. the unique design of the upl2000 allows for an impedance matched transition through the connector, taking advantage of the electromagnetic effects that are so unique to high frequency transmission lines. the signal is contained within the inside surface of the outer shield through the connector in much the same way that the braid of the coax cable contains the electromagnetic energy of the signal within the cable dielectric itself. this effect is more pronounced as transmission frequency rises, as is the case with dtv and hdtv. the connector is offered in the larger diameter cable sizes that are supporting transmission of the video broadcast signal in sta- tions, post-production, and catv headends. hd tv competitor #1 competitor #2 trompeter db of return loss -0 -5 -10 -15 -20 -25 -30 -35 -40 -45 -50 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 note: te st setup includes one foot belden 1505a coaxial cable with bnc plug each end plus adapter and termination. only variable is manufacturer of bnc connectors frequency in ghz upl2000 return loss data

(note that the key technical issue of cable selection is insertion loss over distance). further, the trade off of overall cable diameter, cable weight, and cost are being attended. x - dialog box 17 reasons why trompeter bnc connectors outperform the competition everytime!
