If you are involved with maintenance or have detailed information about navaid transmitter capabilities, the author would appreciate if you listed in the discussion page the following information:


* usual transmitter power for localizer (known to be between 15-25 W) and glideslope (known to be between 5-10 W) equipment.
* usual transmitter power for localizer (known to be between 15-25 W) and glideslope (known to be between 5-10 W ???) equipment.
* usual transmitter power for DME (not VOR) equipment.
* usual transmitter power for DME (not VOR) equipment: various source suggest from 50 W to 1 kW (!!??).
* usual antenna types and gains for localizer and glideslope equipment (for localizer the ERP is known from various sources as approx 100 W, thus assuming 7-9 dBi antenna gain).
* usual antenna types and gains for localizer and glideslope equipment: for localizer the ERP (effective radiated power) is known from various sources as approx 100 W, thus assuming 7-9 dBi antenna gain, glideslope antenna estimated gain 10 dBi <ref>http://www.dbsant.com/gsSpecs.php</ref>.
* usual localizer/glideslope antenna types and gains for various aircraft, for usage by aircraft developers.
