Putting up a vertical antenna part 4 – Antenna built, first measurements
What i have done is create three plexiglass spreader at the base of the antenna, at 2m60 and 5m20 from the base. Through the spreaders i guided 0.5mm copper wire i bought at the DIY shop and fixed the two wires at the base of the antenna.
The big moment. SWR measurements. I hooked up the antenna analyser and got the following result:
What if i switch the connections? Let’s just try it.
Now that looks a lot better! We have a dip around 40m, 20m, 12m (no 15m?) and 10m, so that’s a good start. I wonder if i wired the choke the wrong way? But why didn’t i see that when i put up the antenna last week? Hmmm, questions, questions, questions.
Next step is putting the antenna in its final location and build out the radials set.
To be continued.
