Almost finished!

On October 27, 2009, in Amateur Radio, by TF4M

I have now installed elevated radials which need to be adjusted to bring the antenna to resonance at the correct frequency.

The antenna has a beautiful SWR curve centered on 1775 kHz as measured on my antenna analyzer.

I am able to use the antenna with low power at the low end of the band and I could not resist making a few contacts.

Initial comparison between my previous Top Band antenna – a Double L – on receive indicates that the new antenna outperforms the old transmit antenna by 15dB.

Tomorrow I will adjust the elevated radials and install them permanently.

Beautiful isn´t it?

Traffic Jam in Otradalur

On October 27, 2009, in Amateur Radio, by TF4M

This summer I was given permission by the road authorities to pass the coax cable going to the King through a drain under the road.

The drain pipe turned out to be damaged and when I reported this to the road authorities prompt action was taken.

A new drain pipe was installed two days later enabling me to route the coax under the road.

Traffic turned out to be unusually great that day and 30 vehicles were stuck for a while.
