Lakihegy Diplexer 135.6 kHz, 100 kW & 540 kHz, 150 kW
|
|
The following photos show elements of the diplexer for both frequencies:
|
|
|
Rejection filters for 810 kHz and 873 kHz, frequencies which are radiated from other masts in Lakihegy.
|
|
Rejection filters for 810 kHz and 873 kHz seen from the top
|
Tuning elements of the 135.6 kHz section:
|
|
|
Rejection filter for 540 kHz and
other tuning elements of 135.6 kHz
|
|
On the left side of the photo:
rejection filter for 540 kHz with a coil consisting of two parts which are in parallel in order
to withstand the double
current.
The rotation senses of the two coil parts are in opposite direction.
