In rare cases each transmitter has an antenna system. But in stations where many transmitters are used, this is not always possible, so the outputs of transmitters transmitting in the same frequency band are combined by a diplexer and applied to a single antenna system. (i.e. VHF 1, VHF 2, VHF 3, UHF).or lower frequencies a location with good ground conductivity is required. In case of microwave link chains, stations should be in observable ranges of each other. (see Earth bulge) Computer programmes for the terrain profile and abacs are used in addition to on site observations.
Kofun (å¤å¢³, from Sino-Japanese ancient grave) are megalithic tombs or tumuli in Japan, constructed between the early 3rd century and the early 7th century AD. The term Kofun is the origin of the name of the Kofun period, which indicates the middle 3rd century to early-middle 6th century. Many Kofun have distinctive keyhole-shaped mounds (zenpÅ-kÅen fun (åæ¹å¾åå¢³)), which are unique to ancient Japan.
The Sokuon is a Japanese character representing a small tsu (ã£ or ã in either Hiragana or Katakana respectively).This small tsu quite simply means that the consonant in the next character is âdoubledâ, and a slight pause results.For example, in the word âYukkuriâ (ãã£ãã), the word is pronounced âyuâ (a slight pause of one mora) âkuriâ. The ã£ (tsu) represents this slight pause.his small tsu quite simply means that the consonant in the next character is âdoubledâ, and a slight pause results.
