Been a new ham, I build all kind of antennas; in a process of doing this I accumulated long list of internet references I am sharing below. I will be updating it, deleting old/outdated/not important references and adding new. Due to my present QTH the main focus is compact/limited space antennas, but the list is not strictly limited to this subject. It is a bit chaotic as it originates from the text file I have been dumping my findings to for many month, but proven to be useful, so here it is:
