160m: T160: Vertical half-wave dipoles. Three identical independent antennas are placed on the top of 120m-high heating station' pipe. Dipoles hangs at East, North-West and South sides with a small slope. Dipoles' top is at 110 meters, bottom is at 3...20 meters above the ground. Total length of feeder line is abt. 500 m. Project started in 2006.

80m: T80-1: 2 elements of quad (diamond shape) with parasitic reflector. The antenna is placed on the top of 120m-high heating station pipe, top is at 110m above the ground. Fixed along USA LP/SP direction. Remote switching, positions: forward/back and CW/SSB. Was built in 2006.
•
80m: T80-2: 2 elements of quad (diamond shape) with parasitic reflector. Same as T80-1, the antenna is placed below T80-1, the top is at 70m above the ground. Fixed along JA/Europe direction. Remote switching, positions: forward/back and CW/SSB. Was built in 2006.
•
40m: T40: 4 elements of quad (diamond shape). Same as T80-2, the wire antenna is placed at 70m above the ground and fixed to USA direction. Was built in 2006.
