The utility model relates to the technical field of antenna equipment, and specifically discloses an improved enhanced end-on-fire log-periodic antenna and antenna equipment. The current is sequentially lagged and propagated along the assembly line, the phase difference between the sources is gradually increased, and in order to meet the Hansen-Wood condition, the phase difference is further increased, and the assembly line is lengthened. According to the antenna design, lengthening processing is carried out, and unit spacing is compensated in proportion. For high frequency, it is considered that the high frequency is easier, and more space enlargement needs to be carried out, so that the mutual coupling amount is reduced. The longer the length is, the larger the gain is, theoretically, the gain is further improved, so that compared with a traditional log-periodic antenna, the log-periodic antenna provided by the utility model has the advantage that the array spacing is compensated. And finally, performing mo
