80 meters is very difficult band to take on the road as a portable dipole (inverted V) due the long wires (40mt), the horizontal space required to erect a dipole and the height at which the dipole needs to be supported.
However, my vehicle HF antenna (Bushcomm Highlander 8 multi tap) covers the 8...

This was the first time that I completely drained my batter...

I found that the elevation of the antenna did not work very well in my situation. Lowering the antenna to <3mt above ground seemed to solve the SWR issues, but unfortunately that location w...

The cable is nothing special and doesn't...
Continue reading...To get started on HF I installed a long wire antenna and an Icom AH4 tuner.
The wire runs in NE-SW and is around 22meter long.
The AH4 is is well earthed and uses a shielded multicore cable to connect to the radio in the shack.
