Just as the name implies, it is a dipole antenna which can be rotated so as to optimise the direction of transmission and reception. We know that a

What you are seeing in the infographics is the 160m propagation taken from Reverse Beacon Network over the past one year. It is obvious that most of the

Switched on my radio at around 5.30 pm and I could see the 20m band booming with activity. Few stations from North India were coming in very strong.

Apart from these discussions of my past use of 75 ohms cable and descriptions read online, I have used 75 ohms cable for matching delta loop antenna recently.

I have been trying to optimise my 80/20m loaded coil inverted V dipole antenna for quite some time. Finally I have achieved an SWR of 1.2 on 14200

Have a look at this propagation on Reverse Beacon Network. My CQ call in CW has been picked up by reverse beacon network at a distance of 3263

I had been wondering about how to add extra length of wire for tuning the 20m segment of my 80/20m loaded coil inverted V dipole antenna for tuning.

I had elevated my 80/20m loaded coil inverted V dipole antenna by about 1m, to a final height of about 7m from the ground, to see if the

I had a 40/10m fan dipole with unconventional cone like mounting and I wanted to add elements for 20m. Brought down the existing antenna and unscrewed the 2.5

Just for a curiosity, I thought of checking the capacitance of my antennas with feedline. First I checked the 40/20/10m fan dipole. That antenna has been mounted as
