Also alias call OZ4XL and 5P6T Contest Team.

Ham operator with class A in 2014.
Working with telecommunications and catv.

Im 38 yrs old, one daughter + one dog


       My friend Jesper climbing the tower aug 2016                             4x4elm dk7zb towards sweden + broken flexas

12m tower for 50/70/144/432 mhZ NAC+HF wires   

Trehoeje Hill 102m asl JO46HE 4x4 elm + 1x9 elm

                    45m Contest tower view direction SW

Home antennas (jo46rg):

Tower 12m + 4m top pipe.
Total 81 mtrs above sea level.
65m asl + 16m tower.

I made a support tower mounted to the base so i can tilt the whole thing down to my garden. 

70cm : 4x19 elm "OZ5HF" with power balun + ssb preamp
2m : 9-elm LFA G0KSC + ssb preamp
6/4m :  6elm 6m/5elm 4m G0KSC 4-6-11 homebrew

Wire antenna homemade 30/40/80m dipole wires inv-v. 
10/12/15m homebrew
Vertical 20/40m homebrew

Contest tower (jo46rg) :
65m asl + 45m tower
Total of 110m asl.

GP: Diamond X300 dualband vhf/uhf
70cm : *BROKEN* 1x23 elm Flexa Yagi 7073 for NAC test + HA8ET preamp
2m :     1x11 elm Flexa Yagi FX224 for NAC test + HA8ET preamp
             4x4 elm dk7zb homebrew

The flexas did not last one year in the tower and actually im little dissapointed.
After 3-5 months the 70cm broke from tired metal. But the skinny boom

is wobbling like spaghetti up there and the last 1/3 snapped right after the support boom even with wind on front/back.
I dont understand why boom is so skinny for such a long antenna, but for sure the element system is great+ dipole.
But on 7073 the support boom should have been longer/stronger for stiffening the antenna.
(In my oppinion, the 7056 is the better construction lengt to stiffness ratio.)
On the fx224, the last director is gone, so antenna is now official a "10 ½" elm yagi. 


*update: the fx224 now also snapped right after support boom. Lasted one and a half year, so only 7 elements left.

Instead of fx7073 i will put up 20 year old19elm oz5hf. That will last at least for a while. 
Instead of fx224, i will replace with 1x9elm LFA G0KSC with 30x30mm boom.  


QSL accepted only LOTW and via bureau.
