Hi all;

In working with RF chokes I noticed in several ARRL handbooks the
circuits for amplifiers frequently use an inductance of 22 uh for the
input choke; grid to ground for grounded cathode, or filament to (RF)
ground for grounded grid amplifiers. However the same circuit uses 1 to
2.5 mh choke across the antenna connector. Why such a large difference in
inductance when the frequency is the same (3-30) mc? An explanation would
be appreciated. Thanks.
