Afternoon, February 13 2015 - (at spring 2015 went to history...).
Basic antenna (FD-4) was not effective to make K1N (Navassa Isl).
Quickly made antenna, height 10m GP give me chance on 30m band.
Only 3 different counterweight in the direction ... Navassa of course :)
The antenna tuning best for 17m and 40m - SWR less than 1,3: 1 .
The 30m band is worse, but the efficiency confirmed.
