JA1JRK's Antenna
| The tower over which 4SQUARE(s) of a top band are constructed for the center
Otherwise, 3 Ele Yagi of Low-Band is going up to this tower. In addition, this 3 element Yagi is shortened by the linear loading system which changes a band by vacuum relay, in order to make an input-proof high. 7Ele CQ for 14, 21, and 28MHz in a right tower. 7Ele CQ for WARC-BAND(18 and 24MHz) in a left tower. The Antenna Rotor machine stand of a central tower can be lowered now, and does not need to pull up a mast in maintenance of Antenna Rotor, and the case of exchange, either. Moreover, at the time of a strong wind, the mechanism in which huge 3 Ele is fixed to a tower is also devised. The typhoon season is reduced and collapsed in tower mountain side in order to protect an antenna group. |
