The new antenna on 40m

Installation ECO 247 mast

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. performance1,6kW PEP
Profit4dB/40m, 3,5dB/20m
F / B ratio25dB/20m, 15/40m
Length of boom5m
Longest element13m
PSV1,1/20m, 1,2/40m
Weight26kg

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.
