After more than 15 years of good work in 2006 this fine antenna
due the oldness has ceased to work.
Below is the resulting mini-vna screen showing the antenna's fault
after having noted that no bands were more usable.
So I had to decide whether to buy a new one .... or try to make a repair!
Thinking of the HAM Spirit... and after looking into the money-box
the decision to give a try and look if it would be possible to repair the antenna
was very short.
Part 1 , the Feed_point affair.
As soon as I went to disassemble the various antenna's parts I came across its RF-Feed-Point.
foot base section
There I noted 2 things:
Enlarge in a new window the above pic "foot-base-section" to better understand the story
a) the RF-live contact is just made by the means of a steel screw Y.dot through the antenna tube B.dot and contacting the FeedPoint P.dot .
b) the Feed Point R.dot was broken.
Why the rupture if the antenna is and has been guyed with two levels of cords ?
No idea, but that piece is one of the many that can make the antenna unusable.
The outer plastic base has been glued to close the capillar rupture.
