Dateline 29/06/2016″An interesting observation”

Posted on by 0 comment

23 cm antennes.

First of all the loop yogi was a NTMS design found here
It was built as closely as the normal yagi and it looked good on the VNA so all I can assume is that it was going as best it could.
We know what the new yagi was but just to refresh its this one of these

So the final results are:
Gain difference 60 element to Loop = 5.8db
Front to back = 31db
Gain over dipole = 21db figure quoted on web site is 21.67dbi (my measurement was made between a dipole at the same height and about 1m offset horizontally)
First nulls off of centre lobe are at 14deg both sides and thats pretty much what the poler plot is showing on the web site.

Im very happy with its performance and it has shown me that what I believed was not the case and that was building a yagi at 23cm was a tall order and fraught with problems.
If you want any more information Im only to happy to post what materials I used and may be in a position to supply the hard to get components, mainly the element mounting blocks.

This is just my experience passed on for the encouragement of 23 cm activity.
