Hello all.

A 50Ω wideband impedance transmitter [TX] connected to a RG58 coaxial [====] and to an antenna; in two configurations :

TX=R================================================= aerial

TX==================================================R aerial

Where R is a 50 ohm non-inductive resistor loading at the TX output connector; or, placed at the aerial end of the coaxial  (in parallel to the RF line.)

What differences to expect in behavior / impedance / SWR / performance / attenuation for each case ?
