YU7EF duoband antenna installed at PB7Z

 I took a day off the job to bring the new YU7EF duoband antenna to PB7Z and help to install it in his tower.


Bernard has quite a lot of gear in his garden so assembling the antenna was a bit tight but went smooth.


After mounting the antenna in the tower we checked the SWR with the analyzer to verify everything works like it should.


Final installation. Bernard's tower holds a 2 element steppIR, a PKW 40m dipole, the YU7EF 5/5 duoband and a 2m/70cm beam, on top a vertical I think for VHF/UHF.

We checked signals against the reports we gave each other the evening before with his old 3/3 duoband beam. It was weaker and/or equal on both bands. Since there is always some form of propagation it is difficult to test it this way. One of Bernard's first contacts was with D4L on Cape Verde, his report was +00 on FT8.
