Thanks a ton! The rest of my questions (e.g. false glide slopes with/without flipped modulation frequencies, relevant for above GS approaches) I can calculate myself.
Nice! Question, purpose for three GS transmitters on the tower? I've always believed the lower antenna was phase shifted as required to minimize terrain bounce. Can you confirm/explain? Thanks.
There is only 2 transmitters but 3 antennas. 2 antennas produce the basic GS signal. The 3rd antenna produces added clearance signal and may be necessary due to low clearances or low flyup indications.
When will there be a sequel?I'm really looking forward to it:)

Hi, thanks for this information. Can you recommend good books for those who want to read more about these concepts. Thank you once again

@@Rfinerd Thanks, what is that 3rd (lower) antenna transmitting?
@@TripleSevenAviationFlashcards The signal at the third antenna is phased so the it is predominate 150 Hz.
