On Friday, before CQWW contesto we swapped the main antenna mast. Original 2-14MHz Element DKZ7B we replace the dual-band antenna ECO 247, operating in the 7 and 14MHz:
| Max. performance | 1,6kW PEP |
| Gain | 4dB/40m, 3,5dB/20m |
| F / B ratio | 25dB/20m, 15/40m |
| Length of boom | 5m |
| Longest element | 13m |
| SWR | 1,1/20m, 1,2/40m |
| Weight | 26kg |
The antenna of course received a new Yaesu rotator. Receive antenna in the air require a tremendous effort of all involved, but the result is certainly worth.
