Preparations to put up the Diamond KV-5, a 5 band antenna - PART 3

The fun installation turned out be a complete nightmare.....

The KV-5 was set up at ground level... and it worked really REALLY well.... The SWR was absolutely perfect.  So it was time to put the KV-5 on top of my mast in the back yard.

There it is :)
I was so happy..... But that changed rapidly....
I hooked up the antenna to my ts-480 and tried to tune it.... but.... NO band would tune....
The 5 bands were perfectly set up , but now high above the ground it was totally messed up!

Not having a clue what i did wrong, i wrote an email to Diamond in Japan....
And their answer was pretty clear... "KV5 is required to install at the ground."

I wrote a reply stating my frustration that the manual is not clear at all on the location to install the antenna. There is no note at all that you can not install this antenna on a mast. nor is there a note that you can only install this antenna at ground level.

I called my supplier and he and I came to an agreement that he would take back the KV-5 and supply me with a Falcon OUT-250B , a many band 7,16m long GPA. (google for exact specs....)

So now we have........


I have not had the time to test it really well.... but it tunes on all bands, and it receives more then my weird wire antenna.....
In the upcoming weeks i will see how it works and compares to other antenna's......

Preparations to put up the Diamond KV-5, a 5 band antenna - PART 2

Even though it was really hot outside in the sun , i did some more preperations for putting up the antenna.
I did not make any photo's yet, so I'll add them later.

I started out with a nice trip to the local DIY supply store called Gamma.
I needed some copper pipes,  2 2m pipes, Special ground wire (5 mm wire used in electrical installation)
And some other small parts....

I started with putting the copper pip into the ground... Using water as "drill" you can push 4 meters of copper pipe into the ground EASY.... Don't go deeper with the copper pipe then needed. Copper pipe no goes for 11 euro for a small 2 meter pipe which is the smallest pipe (12 mm).
when that was done i connected the ground wire to the lower wall bracket.
Of course the wire runs through a grey PVC pipe.

When that was done I started to prepare my 6meter long mast pipe. I wanted a possibility to hose a wire antenna to the top, so I made a rope installation.

Tomorrow probably will be the final day of installing the antenna... finally.... but it is said to be really hot again.... If its too hot then i will wait till Sunday where it will be a bit less hot.

Photos will follow later.

Preparations to put up the Diamond KV-5, a 5 band antenna - PART 1

As where i live i do not have a lot of room, i really can only put up a vertical.
So after some research in what is around, and what is "easily" obtained in Holland, i ended up with a Diamond KV-5 a 5 band antenna for 3.5/7/14/21/28 Mhz (80m/40m/20m/15m/10m)

Yesterday i went to Beesterzwaag for a radio fair and bought my antenna......
This morning i started putting the all barckets....
and after that i started to put together the antenna...

We did need some equipment to get the SWR within reasonable value's.....
The MFJ analyzer was just packed again ......

As the wind is quite firm , and the cable and pipe are not prepared yet, the story will continue later or tomorrow or so :) i am not in a rush.....
