One of the reasons some hams don’t wish to participate in amateur radio contests is that they believe they can never win a top spot using simple equipment against thousands of stations.
There are several ways to answer this.
One, you aren’t competing against the big stations in most contests as they usually break down the entries in to level playing fields such as entries for high and low power levels, etc.
Second, you should be thinking of your own contest operation as a challenge to yourself and not to others, to see how well you can do based upon the set up you have and your choice of bands based on propagation.
