One of my hobbies is amateur radio.
Comparing my 10m (28MHz) signals with those of others, I suspect my antenna may be down in effectiveness compared with better optimised systems. My 2W is equivalent to 200mW from the better equipped stations. When fitter (my darn stroke) I may try changing the 10m antenna for something better. A vertical 1/2 wave would be less directional on transmit but might be noisier on receive.
At the present time, my poor state of health is preventing me doing too much outdoors. For example, climbing a ladder is quite out of the question, so I have to live with the antennas I have.
