/!\ I'm still looking for documentation , gain or any other info of this antenna
- as I have no info at all - I would be very happy if someone could mail me some info /!\
I got this Yagi as a present from DK7JQ after
I got licensed in 1995.
The Yagi was dammaged and having had no equippement for 70cm SSB it
layed on the roof of my
parents garage till now (June 2k8).
I decidet to renovate it and to give it a chance even if newer designs
would perform better.
As a student you don't have money so you have to do with what you have
-----Update May 2009 --------
We tried out the renovated Yagi at our University Clubstation and
its performing surprisingly well.
SWR is 1:1,1 :-) so renovation was a sucess.
The balun which was lost was replaced with a construction of a piece of PCB to fit into the clamps
of the antenna balun housing. Matching is done with a 1/4L bypass.
-----------Older text -----------
I had to solve the following problems:
- build up a new balun , cause original is missing (know I got in 95
it but where did I put it...?)
- Find a solution to fix the elementholders ( Elements are in front
of the screw-hole)
this is quite the biggest problem.
- bend it right
- build a boom connector
- look for a new mast clamp
Most is done - only balun and mast clamp are on the todo-list.
This is how I picket it up after years on the roof- Likely all plastic
parts are broken
The element holder system: (above comes the cap making element stable)
The repair procedure :-)
I know it's quick & dirty to work with hotglue , but as I dont know
if the antenna would work I don't want to spend all my student money
So to fix the "dead" element holders i filled them up with
And now the dirtiest ;)
As no efficient solution was found to replace my J - holders I fixed
the elements with hot-glue so that they don't move - no idea what will
happen under heavy sunlight - but I ll see.
Isn't Hamradio about experimenting?
The Balun - empty
The home-made boom conenctor - Made of Zink metal.
The actual status: 3,06m long and taking my hole balcony
