PUNE HAM and Amateur Radio Club (PHARC) eyeball QSO and Antenna Workshop on 2nd August 2015.1.1 PUNE HAMS EYEBALL

It was an  eyeball clubbed with a antenna workshop. We began with a discussion on  Radio wave, Radio Frequency, Wave length, Resonation & Resonant frequencies. While explaining resonant frequencies VU2ASH/ Ashok Joshi used the example of resonation of sound in a dome. He then went on to speak about Velocity factor and velocity factor of transmission lines.

The discussion then moved to Radiating elements of an antenna, Lobe formation of the radiated signals & Ground factor. Ashok spoke about 3dB bandwidth and cut-off frequency of an antenna. Evolution of antennas right from basic half wave dipoles to full length quad antennas were discussed. He explained why a  Dipole works best when hoisted at least lambda by 4 from the ground. Ashok then went on to explain about Termination of an antenna & its resonation, about feed point impedance and the need for Matching networks & baluns. While discussing impedance, Ashok used the example of Dipoles that have a 75 ohms impedance and how when the ends are brought down to 120 degrees to form an Inverted V the antenna impedance drops down to 50 ohms and elaborated on how the impedance of the antenna changes according to its shape.

There were various types of 2m home-brewed antennas that were on display which included a ground plain antenna, a vertical dipole, 3 element tape yagi, a aluminium 3 element yagi antenna with a matching unit, a 3 element quad & a TV ribbon cable slim jim antenna.

We first tuned the yagi made out of measuring tape with the help of a antenna analyser. We stopped briefly for a working lunch that included McDonald’s veg burgers, french fries, lots of Coke some Ice cream with chocolate topping, Kiwi fruit pastry.

After lunch till late evening we went on to construct and test 3 new ground plain antennas.  In all a very fruitful exercise.

  3. Hello Amogh

    First of all i would like to thank you for being generous and helpful in providing all the information about hams operator classes and other amateur radio related information. I checked out your webpage and i really appreciate your efforts in keeping it up with good information.

    Myself, Project Manager and Freelance Web Developer staying near Khadakwasla, looking forward for amateur radio license and have started preparing on my own. But i think it would be great to join some classes for AOSC and understand things in better way from some professional’s point of view.

    Can you please guide me regarding any such classes or amateur radio clubs conducting classes and exams ?

    Thank You.
