New 160m windom antenna on the air

No more yagis, not even a dipole, but a 160m windom antenna is now my main (and only) antenna.

With a total distance of 82m, the longest leg is 57m, this is a monster.  
Everything seems out of proportion when taking a picture of this antenna. 
The height of the longest leg is at least 15m with a sloping ending in the far end of the garden.

Thanks to the ON5ZO construction I'm able to put it so high on a (relatively) simple way. 

More important for me, this construction can be storm and lightning protected within a few minutes.
Because I can only be active during weekends in wintertime, I can put it up on Friday and lay it down on Sunday without too much effort.

160 m windom antenna - 25 m going to the roof of the home - 57 m from the tower to the far end of the garden with in between the on5zo construction to keep it high and divide the forces of the wire.

In order to divide the forces I use a vertical wire to fix the antenna to the 15m high intermediate construction (made for a 80m vertical).  This exists of the old KT34XA alu boom and a 5 m spiderbeam on top of it.  From the construction the antenna wire goes down and is connected to the end of the garden with a second wire.

The connecting part is on the tower where I use the existing basic part of the Optibeam 30m dipole.  Both wires coming from the 4:1 balun are first connected to this tube (protected by to fiber tubes to avoid electrical connection).   This prevents that when raising the tower, a wire tough the alu part and give problems.

It was also a method to quickly switch back to the Optibeam in case of problems with the wire antenna.

Measurements are more than satisfying.
In all CW parts, SWR on 80m/40m/20m/10m is lower than 1,5:1, mostly 1,2:1.  Only on 160m I measure 2,2:1 (resonance occurs at 1740 Khz).

SWR on 30m/15m is slightly higher as expected.
SWR on FT8 frequencies are also around 1,5:1 (160m 3:1).

A first test on 40m in the afternoon gives super results with BV, many YB's, and reception reports in VK
