Concepts of certain basic "Antenna Traps" in 5 Parts:

- To best understand just how any kind of "Trap"
behaves, we first need to look at both
in any kind of circuit.*Inductive and Capacitive effects*

- We need to realize the effect that an Inductive Element or
a Capacitive Element has on the "
".*Length of an Antenna*

- We need to understand how the combination of both the Inductor
and Capacitor behave as either a "
", or as a "*Series Resonant Circuit*".*Parallel Resonant Circuit*

- Then, we need to understand how either of these two Resonant
Circuits may be used as either a "Bandpass Filter",
or as a "
" (known as a "Trap" type of a filter).*Bandpass Reject Filter*

- Finally, we need to see how these are commonly used in an
Antenna System as "
".*Band Traps*

An "Antenna Trap" is simply a Resonant Circuit used to block certain frequencies

Inductors do not like Current Changes

Capacitors do not like Voltage Changes
