| Antennas on loc. RA3 - 10 m band antennas | |
ANTENNAS OF THE BAND OF 10 METERS
In 2006 on a contests position new antenna systems on bands of 10 and 15 metres have been put into operation. Antenna systems are installed on a self-supporting tower in height of 45 metres. Three 8 element antennas "Yagi" on a band of 10 metres can be controlled far off for operation, as in a stack with a direction to the USA, and separately. The upper antenna in a stack, combined with the antenna of a band of 15 m - spun. Stack of antennas "Yagi" earlier used on this direction (3х8 units) has been reoriented to Japan that has allowed simultaneous effective operation of stacks of antennas on two most preferable directions - "the USA-Japan", and if necessary, at the expense of the upper spun antennas of stacks to work in one-two additional directions, depending on concrete conditions of contest and conditions of distribution of radio-waves.
| Stack from three 8 element antennas "Yagi" on a band of 10 m with an azimuth of radiation of 315 degrees (2-4-5 antennas from below). The upper antenna of a stack (16 element, combined with a band 15 m) spun, is available possibility of remote inclusion of antennas of a stack in any combination. | | |
