23cm Antenna

I have built this "junkbox" antenna for my first tests on 23cm with the packet node OK0NJ. The original article was published in the Slovak HAM radio magazine Radiozurnal 1/1998.
The antenna on this drawing is horizontally polarized. If you need vertical polarization, just turn it 90 degrees.
After an hour of work the antenna was ready for tests. I could only check the Radiation Pattern using the transmitter and a simple RF Field Meter.
With the usual 59MHz shift on 23cm, the bandwith of the antenna is more important than the gain. The input impedance should be around 50 Ohms - I don't have any gear to check it.
I hope the pictures don't need any further comments. (Yes, you are right - the green cover is a kitchen case.)
